Guessing is more than pure fun, it's also a key part of kindergarten math. Here's a fun way to bring estimation to the breakfast table.

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.

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