Teaching Matching and Classifying

What it is

Pairs of pictures to judge same or different, two groups to compare as more, fewer or the same, and pairs of objects to compare by height, length and weight.

When a child is ready

Start as soon as the child can match objects one to one.

If they struggle

Draw a line from each object in one group to one in the other. The group with objects left over has more.
