rat or mouse cookie eater

This is a great activity to do alongside baking Numicon biscuits. We use a six Numicon tile as a cutter to create a cookie for each child. Children then bite of one circle each just like the mouse does and see how many circles the have left. On the interactive activity click on a number and see how many circles are left when the mouse has eaten that amount. Click on the mouse to return to the whole cookie. A good activity for simple subtraction.
