5 Kids’ Books that Involve Sets and Sorting

Children look for ways to organize and make sense of their world through play at school and home, as well as at clean-up time. Sorting items into groups by specific attributes gives children the opportunity to define sets according to a rule of what does and does not belong together. Sometimes objects will change classification from day to day. A ball one day may be in the set of things that roll while the next day it might be in the set of toys that goes outside. When cleaning up, children can think about which collection has the most and which has the fewest items. This information becomes useful when choosing how to organize the cleanup and builds the foundation for reasoning about number, shape, and space.

To encourage and develop children’s thinking about sets and sorting, here are five books that are common to preschool and kindergarten classrooms. You can encourage a home-to-school connection by using math books for kids that you possibly already have in your library. Create a check out system for these books and insert these easily downloadable activity cards written in both English and Spanish for families to enjoy together.

Using the books and activity cards both at school and at home will create multiple opportunities for children to engage in the Big Ideas of sets and sorting.
