A simple, colorful, and fun sorting activity to do with your toddler! Sorting is an early math skill. Practicing at an early age is important for understanding numerical concepts and grouping. By sorting, children understand that certain things are either alike or different, and can be organized into special groups! This starts them on the path of applying logical thinking to objects and mathematical concepts. Set up your paper towel tubes, grab your pom poms, and start to sort!
