TGB: bonds to 100
Here are a few questions for you to have a go at yourself.
10 + 90 = 100
50 + 50 = 100
60 + 40 = 100
80 + 20 = 100
100 = 70 + 30
100 = 0 + 100
Here are a few questions for you to have a go at yourself.
Fill in the missing numbers, e.g. 7 + 3 = 10, 70 + 30 = 100.
6 + 2 = 8 60 + 20 = 80 2 + 6 = 8 20 + 60 = 80
5 + 1 = 6 50 + 10 = 60 1 + 5 = 6 10 + 50 = 60
4 + 3 = 7 40 + 30 = 70 3 + 4 = 7 30 + 40 = 70
If I know challenge- teacher example.
If I know 80 + 20 = 100, what else do I know.
E.g. I know
20 + 80 = 100,
100 = 20 + 80,
100 = 80 + 20,
100 – 80 = 20,
100 – 20 = 80
8 + 2 = 10
If I know challenge- you turn!
If I know 60 + 40 = 100, what else do I know?
40 + 60 = 100
100 = 60 + 40
100 = 40 + 60
100 – 40 = 60
100 – 60 = 40
6 + 4 = 10
4 +6 = 10
10 – 6 = 4
10 – 4 = 6
10 = 4 + 6
10 = 6 + 4

Extra challenge
Here are items available in a shop.
Crisps- 40p
Can- 60p
Apple- 20p
Water- 40p
Carton drink- 50p
Pear- 30p
Banana- 10p
Lolly- 70p
Fred has 80p to spend from his pocket money. He buys two things from the shop. Which two things could he buy if he wanted to spend all of his money?
Find all of the possibilities, one has been done for you.
An apple is 20p and a can is 60p. 20p + 60p = 80p.
70p + 10p = 80p
50p + 30p = 80p
60p + 20p = 80p
10p + 70p = 80p
30p + 50p = 80p
40p + 40p = 80p
