Doubling and halving

Doubling and Halving

We are getting very good at knowing our doubles to 20, now we are working on learning our doubles to 40!

Today we looked at halving numbers. It's tricky stuff!

For example we have the number 16. We know that 8 + 8 = 16, therefore half of 16 = 8.
We used butterfly wings and counters to help us halve the different numbers. We used the strategy of equal sharing - we counted the correct number of coloured counters then equally shared the counters onto each butterfly wing.

You could have a go at doing this with your child at home! You could draw your own picture and use all sorts of materials to help your child halve numbers to 40.
