# Doubling and halving

## Doubling

### Little counters and mirror

Place toys on a flat surface, put a mirror next to them and watch how easily you doubled them! This method is the best to understand that to double means to get exactly the same amount again.

### Picnic

Roll play is amazing. You can practice new vocabulary and introduce doubling and halving. Put 2 cups/slices of cake/fruits on a table. Say that you are really hungry and you want to double this amount, and maybe half the amount of garlic on a plate :)

### Numicon and little mirror

Use any numicon shape smaller than 10. It is also great to practice doubles to 20 with this method.

### Take it further using Numicon and Mr Slappy

Kids love using Mr Slappy to find objects. Use the doubles that your child has found. This time call: "Double 5" - and your child's task is to slap double 5. If your child wants to you can count them both together and put the outcome on top.

## Halving

### Pay dough ideas

Play with home made play-dough. Make a pizza/ cake, biscuit and cut it in half. While cutting, encourage the cut from top to the bottom, or bottom to top - it will help with understading fractions in the future.

### Wooden pizza

If your child doesn't like play-dough or you don't like the mess it creates... Buy wooden pizza, but check your toy baskets first, because you might already have it.
