Math Teacher's Got Problems's presents you with a print ready foldable and activity for teaching students how to calculate the volume of rectangular and triangular prisms and pyramids. The foldable breaks down the process by requiring students to calculate big B(area of the base) as the first step, then use the volume formula to solve. A composite figure(composed of a triangular & rectangular prism) is also included. This works perfect as an entry for an interactive notebook or as a stand alone notes. I use this foldable in the geometry unit for 7th grade math, but would be useful as a review for any class studying volume of 3-D figures. Also included is a cut and paste activity to reinforce the concepts covered on the foldable, which is perfect as a math center. Students cut and paste the measurement for big B, the formulas and volume to complete the table(see preview). The foldable paired with the cut and paste activity will engage your students and make teaching volume of prisms and pyramids not your problem! Answer key and directions for teacher use are included.
