Try a 100th Day of School Scavenger Hunt with your preschooler, and send her on the search for objects of different colors!

Celebrate the 100th day of school by creating a geometric, math-inspired mural in the style of Henri Matisse in this creative kindergarten grade art activity.

This do-it-anywhere guessing game helps reinforce number concepts. And it's a blast to play.

The garden is the perfect place to practice math and science with preschoolers. Get digging (and counting, sorting, observing at the same time!)
