Leave no student behind with this differentiated geometry unit on perimeter and area. Over the course of five lessons, young mathematicians explore these foundational concepts through a series of self-selected hands-on activities and...

Fourth graders identify line symmetry. For this geometry lesson, 4th graders are given various pictures and identify if they are symmetrical. Students search through magazines for symmetrical pictures.

Twelfth graders explore a variation of proof. In this geometry lesson, 12th graders apply their knowledge of proof to different scenario. They use 3 different tiers to advance through the lesson.

Ninth graders investigate and make conjectures about volume. In this geometry lesson, 9th graders analyze data and predict the outcome. They calculate volume using different tiers.

Fifth graders complete 3 activities centered around percents. In this ratios, proportions and percents lesson, 5th graders create designs on grid paper that illustrate a variety of percents, solve percent problems mentally, and use...
