Understanding the concept of doubling and halving

Understanding the concept of doubling and halving
Start by matching your fingers to the value on a number card. Can you double the amount? Can you halve the amount?
You will need a 10 frame, 2 sets of number cards to 5 and 1 set of number cards to 10, 10 small counting objects and a part whole model.

Use the 10 frame to work out what a double of the number would be. Transfer to a part whole model. Say the sentence “One part is ____ and one part is _____. The whole is _____.”

If you are green standard then make sure you can say the sentence and then see if you can calculate by drawing circles to represent the objects.

This is a part whole model. You could draw your own.
