What are polygons? Learners find the perimeter of various geometric figures that the teacher has drawn in chalk on the sidewalk. A worksheet to record their measurements is provided. Get your third graders outside and exploring the world...

Seventh graders calculate the area of certain cages at the Miami Metrozoo after observing a teacher demonstration.

Sixth graders use number cubes to explore volume of two-dimensional shapes. They roll a die and construct a shape using the numbers rolled as measurements of the sides. They estimate the volume of a given object, and then use the...

Are you feeling the pressure? Let loose a little with a kinesthetic activity that models molecular motion in a closed space! The activity varies conditions such as volume and temperature and examines the effects on molecules.

Cutting the cheese isn't a joke. Scholars observe a wedge of cheese and must determine how to cut it in half horizontally. They apply their knowledge of sectors to determine the most accurate way to slice the cheese.

In this online math worksheet, students calculate the surface area of a variety of spheres. This excellent resource allows the students to check their answers, and to get "hints" should they run into difficulties. A terrific teaching tool!

Students explore how the Pythagorean Theorem works and how to apply it.

Fifth graders design their own house, while also using problem-solving skills involving perimeter and area. They exchange houses with a partner and find the perimeter and area of the window, doors, and front side of the house.

Students are introduced to the Pythagorean theorem. They use three different activities that give students the opportuntiy to observe triangles, and use the Pythagorean theorem and practice different ways of determining areas of...
