Second Class Maths | Scoil Oilibhéir Naofa

Second class

During the month of October 2^nd class children will be learning about comparing and ordering, addition and subtraction in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

add, subtract, take away, is the same as, equals, difference, greater than, less than, count, number sentence, column, row, frame

100 square, between, above, below, left, right, greater than, less than, starting at, ending at, count, count on, count back, row, column, digit

Practical games and activities – Here are some ideas to do at home:

Comparing and Ordering;

-Use lots of hands-on activities to reintroduce your child to comparing and ordering. Practise using the symbols associated with more than/less than/same as. A strategy to remember the symbols is as follows-the open side of the symbol is similar to a crocodile’s mouth and always ‘eats’ the bigger number, e.g. 36>15 and 19<42. Another strategy is to say that the bigger number always points at the smaller number.

-Ask the children to identify situations where they can use the language of more/less/same as.

Addition;

-Use lots of hands-on activities to reintroduce your child to addition. Physically adding objects to a set to see how many are there now.

-Create addition sentences-for example, 6 children like apples,4 children like bananas and 7 children like pears. How many children like fruit altogether?.

-Beat the clock-Give your child a number, e.g. 20. Using a timer, give them 1 or 2 minutes to write down as many different combinations as possible that total to 20.

Subtraction;

-Use lots of hands-on activities to reintroduce your child to subtraction as deducting. Physically taking away objects from a number of objects to see how many are left.

-Use a tens and units template and some cubes/lollipop sticks.

-Create subtraction sentences- for example, there are 43 sheep in a field, the farmer forgot to close the gate and 11 escaped, how many sheep are in the field now?

During the month of September 2^nd class children will be learning about addition, doubles and near doubles in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

More than, less than, equals, the same as, higher, lower, bigger, smaller, greater than, add, plus, altogether, in total, double, total, combine, near double, group

Practical games and activities – Here are some games to play at home:

Games: Snakes and ladder, 100 square game, addition bingo and doubles bingo (make a template with the sums and the bingo caller only calls the answer and vice versa)

*the children must remember to use their doubles and near doubles

Listen and count; use a tin can and marbles to encourage children to count on, for example: ‘there are 17 marbles in my tin. Listen and count on as I drop in some more.’

Go fish; Place number cards on the table face down. Give the children a target, e.g. ‘Today we are making a total of 14.’ The children take turns at picking up 2 cards. If the total is 14 they keep the cards. If not they place the cards back down.

Double trouble; Place number cards down on the table face down. The children take turns picking up two cards, looking for doubles. When they find two cards that are the same they must answer correctly to keep the cards. If they answer incorrectly the cards are returned to the table.

Problem Solving: There are 9 girls in a class. There is double the amount of boys. How many boys are in the class?

How many children in total are there?

Six more girls join the class, how many are in the class now?

During the month of June 2^nd class children will be learning about capacity in their maths lessons while also revising fractions, time and money.

Maths Language – Here is the vocabulary that the children will be learning:

-full, empty, almost full, almost empty, compare, estimate, measure, litre, half, quarter, container, hold more, holds less, capacity, fill

Practical games and activities – Here are some activities to do at home:

Your child should understand capacity through estimating, measuring and recording the capacity of a wide variety of containers using non-standard units. They should select and use appropriate non-standard measuring units and instruments; and they should estimate, measure and record capacity using litre, half litre and quarter litre bottles and solve simple problems.

Here are some ways you can help your child with this topic:

-Use a number of different-sized containers; investigate which holds more and less. Investigate which container is best for investigating capacity, e.g. would you use an egg cup or a jug to investigate the capacity of a bucket?

-Revise how many cups/eggs cups/glasses etc. it takes to fill a litre container. Always encourage your child to estimate before measuring.

-When shopping source different shaped litre containers.

-Introduce containers that hold half a litre and a quarter of a litre. Investigate how many smaller containers it takes to fill each half litre and quarter litre container. Estimate and then measure.

-Remember hands-on activities will help your child to understand this concept. The more activities the child takes part in the easier the concept is to understand.

Have fun!

During the month of May 2^nd class children will be learning about weight and subtraction in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

-weight, heavy, heavier, heaviest, light, lighter, lightest, the same as, non-standard units, kilogram, grams, appropriate, balance, scales, weigh

-tens unis, number, less than, more than, minus, take away, subtract, how many more? How many less?, difference between, forwards, backwards, symbol, sign, equals, rename, greater than, less than

Practical games and activities – Here are some activities to do at home:

Weight

Your child should estimate, compare and record weight using non-standard units, select and use appropriate measuring units and instruments; estimate, measure and record weight using kilogram, half kilogram and quarter kilogram and solve simple problems.

-Continue to emphasise the importance of estimating. Estimate first and then work out the answer.

-Last year your child was introduced to 1kg. Using a 1kg weight, e.g. a bag of sugar, investigate the weight of different objects at home, e.g. favourite toy, shoe, book, game, 3 apples etc. Again ask your child to estimate first if they think the object will be lighter or heavier than 1kg.

-Introduce something that weighs a half a kilogram. Find objects around the home that are lighter than half a kilogram, the same as half a kilogram, and heavier than a half a kilogram. Look at the weight of food items.

-Repeat this for a quarter of a kilogram.

-When shopping in the supermarket, see how many items can be found that weigh half a kilogram and that weigh a quarter of a kilogram. Compare the sizes of these items- large doesn’t inevitable mean heavy. What’s the biggest item you can find that weighs a quarter of a kilogram? What’s the smallest item to be found that weighs 1 kilogram?

Subtraction

-Give your child a tens and units template and some counters (cubes, lego pieces etc.) Make up some basic number stories and read them aloud for your child. For example, Joe the clown had 19 balloons. 7 of them blew away in the wind. How many balloons had he left? Break it down slowly to ensure complete understanding. Ask your child to show you 19 on their tens and units template page. Tell them seven blew away- they must show this on the template (remove 7 units).

-Repeat this calling out number stories and getting the children to work them out in pairs. Mix up the stories so that the children don’t think very problem is solved the same way.

During the month of April 2^nd class children will be learning about money, symmetry and area in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

-money, coin, cent, price, euro, spend, sell, pay, buy, change, costs less/least, costs more/most, equals, exchange, cheap, cheaper, cheapest, more/most expensive, total cost, amount, altogether, same value as, how much

-symmetry, symmetrical, non-symmetrical, fold lines, axis, fit, half, mirror, reflection, match

-cover, surface, estimate, measure, edge, flat, overlap, fit, space, gap, surface, same area as, smaller/greater area than, compare

Practical games and activities – Here are some activities to do at home:

Money

We will be continuing to learn about money this month. This time we will be moving onto €2. Here are some activities to help;

-put some coins into a purse for your child to count. Encourage them to write down the amount they have. Repeat the activity, while continuing to change the coins in the purse.

-Now tell your child to write down an amount you want them to make with the coins (up to €2)

-While out shopping, draw your child’s attention to the price of everyday items. Involve him/her when paying at the till. Show them the coins you are using and any change you receive. They could help you count out the correct amount or help to check your change.

-If there are ‘sale’ signs or if you are using money-off tokens, bring these to your child’s attention and help them to work out the new price.

-While at the shops, give your child some problems to solve, e.g. If I have €2 could I buy a packet of sweets? Would I get change? How much change would I get? Change the question to suit items available.

-Lots of experience calculating change is essential.

Symmetry

Shapes that fold in half so that one half folds exactly on the other half are symmetrical. The fold line is the line of symmetry.

-Find objects at home that have 1,2 or more lines of symmetry, e.g. a vase is usually symmetrical but a jug is not.

-Look at pictures (images of flags are good) to see if they are symmetrical.

-Cut out 2D shapes and see whether they have a line of symmetry.

-Write out letters of the alphabet (in capitals) and the number 0-9 and see if they are symmetrical.

-Do some blob painting; fold a page in half and open it again. Put some blobs of paint on one side only, then fold the paper together and press firmly. When you open the page again you have a symmetrical shape.

-Draw half of some simple pictures on squared paper and ask your child to copy the picture to complete it. If your child finds this difficult, use very simple shapes- heart, triangle, square etc.

Area

The area of a shape is the amount of surface that the shape covers.

-Ask your child which objects have the greater surface area, e.g. the kitchen table or the coffee table, the bathroom floor or the sitting room floor.

-Get them to identify 2 objects that have a bigger/smaller area than a given object, e.g. a tray.

-Draw a rectangle on squared paper and ask your child to count how many squares make up the rectangle. Ask them to draw a smaller /larger rectangle than yours (on squared paper) and again count the number of squares

-Get your child to estimate how many books will cover the rug. After they have estimated get them to measure (leaving no gaps) and record the right answer. Explain that their estimate does not need to be the same as the right answer. Next use something larger to measure, e.g. a pillowcase. Estimate how many pillowcases will cover the rug. They will find that they need fewer pillowcases than books to cover the rug. Now try something smaller, e.g. a playing card. They will find that they need more playing cards than books or pillowcases to cover the rug. We know that we can measure surface area with many different objects and that some objects are better at covering surfaces than others.

During the month of March 2^nd class children will be learning about Money, 3D shape and Addition in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

-money, coin, cent, price, euro, spend, sell, pay, buy, change, cost less/least, more/most, equals, exchange, cheap, cheaper, cheapest, more/most expensive, total cost, amount, altogether, same value as, how much?

-cube, cuboid, cylinder, sphere, cone, 3-D, 2-D, shape, faces, edges, corners, slide, stack, roll, curved, straight, solid, net

-count, add, make, combine, plus, altogether, in total, addition, more, form, group, all, count on, double, near double, double plus one, swap, split, how can we make?, how many altogether? how many more do you need to make?

Practical games and activities – Here are some activities to do at home:

Money

-Playing shop at home can give you child practice in using and exchanging coins. You can use any household items for the shop- toys, cans of food, shoes, etc. Price the items using the values 1c, 2c, 5c, 10c, 50c and €1. In the next few months we will move up to €2. Get your child to write the prices out on small slips of paper.

-Practise different ways of making up the prices using the coins, e.g. I can make 50 cent using one coin; can you make it using 3 coin? Now exchange a €1 coin for 2 coins that will make up that value.

-Playing shop also gives excellent opportunity for your child to practise giving change from €1. Encourage your child to count on when working out the change, e.g. if an item costs 75c, count on 5c to 80c, then count on a further 20c to €1, so they give 25c change.

-Get your child to take 4 coins out of a small bag. Once they have added the coins together, get them to write the amount on a piece of paper or small whiteboard. Repeat this using a different number of coins.

3-D Shapes

-The shapes we will be looking at include sphere, cylinder, cube, cuboid and cone. Your child should be able to describe, compare and name these shapes.

-Have a 3-D shape hunt in the kitchen or in a shop- it is important that children can identify shapes in the environment, e.g. a cereal box is a cuboid, a tin of beans is a cylinder, an orange is a sphere, a die is a cube and a party hat is a cone. Ask your child to examine and then describe each shape- the number of faces, corners and edges.

-Draw around 3-D shapes to see which 2-D shape you find, e.g. draw around the face of a cylinder and you get a circle

-Play ‘Guess the Shape’- you describe a shape and your child has to identify what shape it is. Your child then describes a shape and you must identify it.

-Check which 3-D shapes are best for building, i.e. that fit together well. Use a variety of building blocks/3-D shapes. Look at buildings when you are out and about and discuss their shape.

-Investigate whether 3-D shapes can slide (you could set up a ramp), stack and roll.

Addition

-The children will be learning different strategies for adding bigger numbers. They will be exploring doubles and how they can help when adding.

-When adding doubles, your child is encouraged to split up the number into tens and units, e.g:

16+16 is the same as 10+10+6+6

(10+10) + (6+6)

20+12= 32

In the same way, when adding larger numbers they are asked to split up the number:

75+24 is the same as 70+20+5+4

(70+20) + (5+4)

90+9=99

Another strategy the children use is:

19+7 is the same as 20+6, so 19+7=26 – Add 1 to make 20 / Take 1 away to make 6

Add 1 to the larger number to move it to the nearest 10, then take away 1 from the units column. Ask your child some similar questions to help them develop this method, e.g. 19+6, 29+7, 39+4. Exploring some of these strategies at home with your child will help them to develop more confidence when adding bigger numbers in the classroom. Ask them to talk through the method they are using when answering addition problems.

Second class

During the month of February 2^nd class children will be learning about time and subtraction with the 101-200 square in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

-o’clock, time, hours, minutes, digital, o’clock, half past, quarter past, quarter to, next, before/after, late/early, later/earlier, long/short hand

-pattern, what comes next?, recognise, jump, 101-200 square, odd, even, beside, before, after, above, under, row, column, table, subtract, back, hundreds, tens and unit

Practical games and activities – Here are some games to play at home:

Time

-Talk to your child about forthcoming events- family birthdays, St. Patrick’s Day, summer holidays, First Holy Communion, the seasons, months, dates etc.

-Have a weekly timetable/calendar on display in your home. Work on saying in order the days of week, months of the year and seasons.

-Revise how to read one hour and half hour intervals on a clock. Point out that when the long hand points to 12 we say o’clock, when it points to 6 we say half past (this was taught in 1^st class). This year the children are learning how to read a quarter past and a quarter to an hour- when the long hand points to 3 we say a quarter past and when it points to 9 we say a quarter to.

-Talk aloud, ‘It’s 9 o’clock- nearly bedtime.’ ‘We are leaving at half past 8’.

-Time your child doing simple tasks and talk about the amount of time that has passed.

-This year we are also beginning to read digital time- 4.00 or 4 o’clock, 5.30 or half past 5. Point out the time on clocks, watches, computers, timetables, posters etc.

-Make a clock using a paper plate, ask your child to show you various times. Call out digital times also and ask you child to show that time on their analogue clock. Be careful with ___.45.

101-200 square

-Make a blank 101-200 square. Allow your child to fill in the numbers.

-Use this 101-200 square to practise skip counting in 2’s using a counter. Repeat counting in 3s, 4s, 5s, 6s and 10s.

-Use one colour counter for counting in 3s and another colour counter for counting in 4s. Did you notice anything?

-Repeat this activity for counting in 5s and 10s, then for counting in 3s and 6s.

-Pick a number from the 101-200 square. As what comes before/after this number. What number is directly above/below this number?

-Ask you child to place a counter on a number, e.g. 108, then count back 4 numbers and place a counter on the number they land on. This number represents 108 minus 4.

-Try subtracting multiples of 10. You are taking away 1 ten and 0 units.

Second class

During the month of January 2^nd class children will be learning about length, subtraction and place value in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

-long, short, longer, shorter, longest, shortest, small, big, smaller, bigger, tall, taller, smallest, biggest, tallest, span, width, height, length, measure, metre, centimetre, metre stick, stride, estimate, shorter/longer than 1 metre, about the same as 1 metre

– Tens, units, less/more than, minus, take away, subtract, how many more/less?, difference between, equals, number, forwards, backwards, symbol, sign, equals, rename, greater than

-Hundred, place value, set, digit, altogether, separate, group, on top of, over, beside, before, after, rename, tens, units

Practical games and activities – Here are some games to play at home:

Length;

-Using non-standard units of measurement (pencil cases, spoons, pillows, crayons, straws etc.) to measure the width and length of the table/counter/bath/bed etc.

-Measure the length and width of the bathroom/kitchen/hall/table etc. using spams.

-When out walking measure the distance using strides from the house to the entrance of the estate and so forth.

-Make a metre using wool or string. Look for items around the house that are the same/less than/equal to a metre.

*Always remember to estimate before measuring.

Subtraction with renaming

One of the most difficult concepts in second class is subtraction with renaming.

Activities; use lots of hands-on activities, give the children plenty of hands-on practice at physically taking away objects from a number of objects to see how many are left. Make a tens and unit template, collect a variety of materials (lollipop sticks, beads, Lego etc.) from around the house. Give your child a sum, for example 65-46; they must use their objects to work it out.

Poem;

More on the floor

Go next door and get 10 more

Numbers the same

Zero is the game

Place Value

-We have already explored place value 0-99. Now we are moving on to bigger numbers, up to 199. The hundred part of place value is introduced.

-In school we will be using notation boards and an abacus to help understand place value of numbers up to 199.

-Make a hundred, tens and units template at home. Call out a number and allow your child to create this number on the template.

-Lego or building blocks are great for making 10 groups of ten which is equal to one hundred. Using the Lego and a tens and units template repeat the above activity.

Second class

During the month of December 2^nd class children will be learning about Addition with renaming and Data in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

-tens, units, make, add, plus, altogether, equals, total, bundle of ten, combine, join, count, group, notation board, how many?, count forwards/count on, what comes before/after/between?

-Sort, classify, more, less, the same, altogether, order, block graph, most, least, how many more?, how many less?

Practical games and activities – Here are some games to play at home:

Addition with renaming;

Your child is learning about addition to 99. Renaming is used in addition where there are more than 9 units. Take 15 lollipop sticks. We bundle them together to make a group of 10. We have now renamed the units. They become 1 bundle of ten and 5 units.

Remind your child to always add the units first. Encourage them to line the numbers up correctly underneath each other when writing an addition sum.

-Call out a number and allow you child time to make that number using straws/lollipop/notation board sticks, e.g. for 24, they must place 2 bundles of 10 in the tens column and 4 units in the units column. Repeat for several numbers.

-Revise addition without renaming using these resources on their notation board.

-Then move onto simple addition sums with renaming using the same resources and their notation board. Call out the sum 24 + 8. Your child will place 2 ten bundles in the tens column and 4 units in the units column. Then they place 8 units in the units column. Combine the units together and combine the tens. Now we have 2 tens and 12 units. Look at the 12 units. Can we make a stick of ten? Now we have 3 tens and 2 units. The total is 32. Repeat this activity several times until your child can repeat the process without help.

Game: ‘Beat the Clock’

Your child completes 5-10 sums while trying to beat the clock

Data;

Your child should sort and classify objects on the basis of two and three criteria. Your child should also represent, read and interpret simple tables, charts and block graphs.

-Give your child a magazine catalogue from a supermarket. Go to the special offers page. Ask your child to cut out all of the special offers and put them in 3 or 4 groups- dairy products, fruit and vegetable cleaning products etc. Using glue and some large pieces of paper create a pictogram using the pictures. Discuss the pictogram with your child, e.g. how many more dairy products are there than cleaning products? (A pictogram uses pictures to represent the data; block graph uses a block for each piece of data).

-If your child has a party coming up, ask them to find out from their friends which activity/what food they would prefer. Give them several pieces of paper the same size. Ask them to write or draw one activity/food on each piece of paper. Create a table/graph of the results. Discuss how many chose each activity/food- which was the most/least popular? What was the difference between ____ and ____?

You can have lots of fun developing this concept at home.

During the month of November 2^nd class children will be learning about Fractions in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

Whole, half, quarter, four, two, one, equal, parts. Share, split, divide

Practical games and activities – Here are some games to play at home:

Games:

–Make pizzas; put pepperoni on a ¼ of the pizza, ham on another ¼ and chicken on a ½ of the pizza

–Draw a shape and ask the children to colour half/quarter of the shape

–Doubles are very important for fractions so set a timer for a minute, see how many doubles you child can answer in that time

Challenge : Can you list all doubles 1-10 in 30 seconds ???

Problem Solving:

Tom cut the pizza in quarters; there were 3 pineapples chunks on each quarter.

How many chunks of pineapples were there on the whole pizza?
How many chunks of pineapple were on half of the pizza?
How many chunks of pineapple were on three quarters of the pizza?

During the month of October 2^nd class children will be learning about place value, angles and 2D shapes in their maths lessons.

Maths Language – Here is the vocabulary that the children will be learning:

Ten, unit, number, set, place value, digit, altogether, separate, 100 square, group, more, less, on top of, over, beside, before, after, underneath, below, above, big, bigger, small, smaller

Corners, angles, square corner, right angle, greater than, less than, straight lines, fits exactly, rotation, full turn, half turn, quarter turn, half turn, right left

Square, rectangle, triangle, circle, semi-circle, oval, 2-dimensional, construct, side, corner, straight, curved, round, point, flat, edge, half, quarter, fit together

Practical games and activities – Here are some games to play at home:

Place value is all about understanding the value of each digit within a two-digit number. In school we will be using notation boards to understand place value up to 99. It is very easy to create these at home to practise place value. Practise breaking up certain numbers into tens and units. For example call out 32. Your child should be able to identify that this is 3 tens and 2 units.

-Using lollipop sticks call out a 2 digit number. Your child must represent that number using lollipop sticks.

-Give your child a bunch of lollipop sticks; they must divide them into groups of tens and units.

An angle is formed when two straight lines meet. An angle is another name for a corner.

-Play Simon says at home- give instructions such as ‘Simon says; jump a quarter turn to the right, take a half turn to the left’ etc.

-Check objects that rotate/turn and form angles, e.g. the dials on the hob, clock hands, scissors etc.

A square corner is known as a right angle. Ask your child to find angles that are smaller than, equal to or larger than a right angle.

2D shapes; squares, rectangle, circles, triangles, semi-circles and ovals

Help your child draw, trace around and cut out these shapes, make them using play dough and find them in your home, e.g. a biscuit, a cream cracker, a tortilla wrap, playing cards, a birthday card, a picture frame etc. Draw your child’s attention to the shape of windows, doors, plates, tiles etc.

-Go on a 2-D shape treasure hunt outdoors

-Play I spy, e.g. ‘I spy with my little eye something in the shape of ….’.

-Make 2D shapes using lollipop sticks and playdough

-Make new 2D shapes; cut out 2-D shapes and make new shapes by folding then in half/ quarters

-Art attack- create a picture by combining 2-D shapes shape printing

Time; clock, time, hours, minutes, digital, o’clock, half past, quarter past, quarter to, next, before/after, late/early, later/earlier, long/short hand

Practical activities – Here are some activities to do at home

Activities Weight;

-Get a 1kg bag of sugar; allow your child to hold it so they can become familiar with what 1kg feels like to hold. Ask your child to find objects around the house that they believe would be the same as, less than and more than 1kg. Repeat these activities with ½ and ¼ kg.

-While cooking and out shopping encourage your child to find items that are 1kg, ½ kg and ¼ kg.

-Engage in cooking activities, allowing your child to weigh the ingredients.

Activities Fractions;

-show your child and apple. Cut the apple into two equal parts-the apple is now cut into two equal halves. Cut another apple into two pieces that are not equal. Clearly show that one piece of the apple is very small and the other is very big.

-Give your child a selection of the same object- be sure it is an even number. Ask them to half the set. Repeat the same activity and ask you child to split the set into quarters.

Activities Time;

-Make a clock using a paper plate. Fold the clock in half from 12-6. Fold it again. On opening the paper clock the children will see where a quarter of an hour starts and ends.

-Ask your child so show you a variety of times (both analogue and digital) on the clock.

-Game; how long is a minute? Ask your child to close their eyes and guess how long a minute is.

-Game; Snap. Print out clock faces, digital times and written analogue times. The children must match the clock face to the written analogue or digital time.

During the month of April 2^nd class children will be learning about Money again in their maths lessons. Money can be a difficult concept for children to grasp; it is so important that children use money in real life settings.

Maths Language – Here is the vocabulary that the children will be learning:

Money, coin, cent, price, spend, pay, buy, change, costs less/more, cheap, cheaper, cheapest, most/more expensive, same value, how much?

Practical activities – Here are some activities to do at home

Activities: set up a shop at home, give all items a price. The children must add up the total bill and give change from €1 and €2
When going to the shop get the children to purchase the items, they must work out the total bill and the change
Look at the prices of things while shopping; what is the most/least expensive
Compare the price of items in Tesco, Aldi, Lidl, Dunne Stores etc. and discuss which has the better value

I went to Aldi and I bought a bag of oranges for 93c and an ice cream cone for 49c.

What was my total bill?

What change did I get from €2?

What coins make that amount?
