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.

Use reusable, recyclable materials--along with a dose of imagination--to build a castle with first grade geometrical forms.

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

Does your fifth grader need a study buddy for geometry? Forget about a tutor. Help him make his own geometry dictionary!
