Here's a Halloween, math activity: have your preschooler or pre-kindergartener carve shapes into a Jack-O-Lantern face and boost her shape recognition skills.

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

Build your child's vocabulary by exploring and discussing spatial relationships during everyday activities such as building, rearranging, and ordering.

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