Forget the measuring stick! This fun math activity uses a body part, your child's hand, as a ruler.

Help your child learn science and math skills like sorting, sequencing, and ordering while taking a nature walk and collecting and collaging leaves.

In this simple and social activity, children use size comparison skills to find objects in nature that are bigger, smaller, longer, and shorter.

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

Challenge your preschooler to a game of shape match-up--an entertaining way to boost her observational ability.
