 You can help a child learn about more and less by putting some small objects into groups. For this activity, you can use any objects you have available, but for my example, I'll be using rocks. So we'll put two rocks in one group, and we'll put three rocks in another group. Now together, you and the child can count out how many rocks are in each group. We have one, two rocks in this group, and one, two, three rocks in the other group. Then you can ask the child which group has more and the child can point at it. Then you can ask them which group has less. You can change up the groups and ask the child which group has more and which group has less. When a child learns about more and less, it helps them when they learn to add and subtract.
