 Here is a sorting activity you can use to help a child learn to compare sizes. For this activity you can cut out some paper squares of different sizes, small, medium, and large. And then you can ask the child, can you help me sort these into different groups? We're going to sort the small ones together, medium ones together, and the large ones together. You can show them how to do it for the first group. I'm going to sort the small squares over here, and then you can ask them to do the rest. So they can sort the medium squares, and then the large squares in another group. This sorting activity will help improve the child's logical thinking.
