This activity introduces complementary and supplementary angles and is appropriate for students in grades 5 – 8. This whole class activity supports CCSS 7.G (Solve real-life and mathematical problems involving angle measure, area, surface area, and volume.) and addresses visual and kinesthetic learning styles. There are two sets of angle pairs, a complementary set and a supplementary set. Each student is given an angle piece that has a complement or supplement "match" and they move around the

A quick interactive whiteboard activity to reinforce the differences between prisms and other space figures. It can be used as a whole class activity where students take turns deciding whether a particular shape is a prism or not.

This activity addresses CCSS 8.G.B.7 and utilizes SMART Response "clickers" to practice problem solving using the Pythagorean Theorem. There are 10 real world problems that will challenge your students while working individually or in small groups.

Students explore the concept of geometric probability both theoretically and experimentally using fractions, decimals, and percents. After finding the theoretical probabilities of hitting the targets by finding the areas of the polygon targets and the square dart board, students get to place the darts on the dart board to find the experimental probabilities of hitting the targets (which are hidden). Offering small classroom prizes for students that hit the target adds to the fun in this engagi
