Hey pupils,

Here are some number games.

Number Bonds to 10

Number Bonds 10 with a twist

Make 15

Fishy Count

P2 pupils to try the 1st three games and see how fast you cancomplete the game. It will help you in your addition and subtraction.
P1 pupils do try all the games.

Use the eye to cover part of it. You can ask your child 3 and ___ make 10. Then your child can check by adding in the beads.)

we were using 2 different colour cubes to make our number bonds.

How to teach Number Bonds

From the previous post (Number Bonds), you would have realised that Number Bonds help pupils relate addition & subtraction. It helps pupils relate to part(a) + part(b) = whole or whole-part(a) = part(b) or vice versa.

If you have attended our P1 Parents Maths @ Home workshop on Friday, we would have shared with you strategies and manipulatives that you can make @ home. However if you did not attend the workshop, let me share with you some of the strategies. I will try my best to write it as short and and as easy as possible. However, if you are unable to understand it, do give me a call and I can demo to you.

1 manipulative that you can use @ home is Hangers & Clothes Peg. Refer to the picture below.

You need

clothes peg (2 different colours if possible)

hangers

flashcards with numbers

Think of a 2 numbers that would give a sum within 10. For instance 2 and 5 makes_______.

Ask your child to clip the pegs on the 2 ends. Each part represents 1 number.

Move the 2 parts up to the clown face(pupils have been told that whole is head and the 2 parts are like hands) and now they have 7 pegs.

Put the whole number in the clown face(7).

To teach whole-part= part

Put the the pegs in the whole part(7) and then tell the child that 1 part is 4 and ask what is the other part. You can use flashcards to show the known part(4).

Pupils move 4 pegs to the known part. There are 3 pegs left in the whole and they can see that the unknown part is 3.

Practise this a few times.

Next introduce to them the sentence/diagram where the whole and 1 part is given and they have to find the missing part.

Instead of hangers, you can use 2 different coloured cups/bowls to show the whole is made of part & part. 1 colour(eg: red) for the whole and for the parts(eg: blue).

Tips:

Show a number bond and ask pupils to identify the whole and parts. Use different shapes and rotate the number bonds around. Look at the examples below.

Teach the pupils that part and part makes whole first.

When and only when they are comfortable with it that you lead them to whole-part=part. Let them practise it.

Parents, if any problems helping your child with Numbver Bonds, do drop me a note and we shall

work together.

Thank You.
