 Here's a tasty way to help a child learn about subtracting. You can use a food that they enjoy, like some bread, that can be broken into small pieces. For example, you could put six small pieces in front of the child and ask, how many are there? The child will count them and say six. You can have the child eat two pieces and then ask, how many are left? The child can count and say four. You can respond, that's right. You had six pieces of bread, then you ate two, how many were left? And the child can say four. You can repeat this using different amounts. This is a fun way to help a child understand subtracting.
