Invite your first graders to compose and decompose two and three-dimensional figures with this fun, hands-on lesson plan. They investigate and predict the results of putting together and taking apart two-dimensional shapes with rubber...

Compare geometric solids based on their properties. Your emergent geometers use spaghetti and marshmallows to build models so they can examine the number of faces, edges, and vertices on polyhedra of their own creation. Resource includes...

Students identify and create simple geometric shapes and describe simple spatial relationships. Through discussion, hands-on activities and show and tell, they identify geometric solids in real life and create graphs of commonly found...

Tenth graders investigate the history of geometry and its different shapes. In this geometry lesson, 10th graders practice seeing three dimensional shapes and explain why there are only five polyhedra. They relate all the new materials...

Space scientists use water displacement to determine the mass of a cubic centimeter mini meteorite, and then use it as a small-scale representative of an asteroid. They figure out the orbital velocity of an asteroid. Then they use a...

Students explore the possibility of an asteroid hitting planet earth. For this planetary lesson students complete a lab activity to see the effects of an asteroid hitting earth and compare different craters.
