Option one: Grab a basket and quickly walk around your home. Add anything red, yellow, or blue to your collection.
Option two: Ask your child to collect red, yellow, and blue toys they can find around the house.
Invite your child to color sort and count the toys found.
Notes
Extension: This color activity extended on its own! My four-year-old enjoyed this activity SO much that he wanted three more colors added. To extend this color-sorting game, we added three additional colors! My preschooler went around collecting, sorting, and PUT AWAY the objects! (gasp!) A serious winning situation!
