Number Bond Blocks

Aim of the Game:

For children to be able to confidently add, they need a good knowledge of number bonds. Start with bonds to 10, 20 then 100. Number bonds are two numbers that add together to make a given number. Once children are secure with these they will find mental addition and more complex addition questions much easier. But they are challenging for some children to remember so, as always, my recommendation is to turn the learning into something simple but fun.

What do you need?

• Megablox or Duplo Blocks
• Whiteboard pen

How to Play:

• You need one double block and the rest singles.
• Ask the children to write all the number bonds to 20 on the single blocks, then mix them up on the floor and time how long it takes for them to build a number bond to 20 tower.
• Then challenge them to build the tower in order starting with 0+20.
