All you have to do is hit print and hand out to your students to cut and sort! Students take these 30 strips and organize them into 10 groups (word, picture, description). Terms include complementary angles, supplementary angles, angle bisector, congruent, vertical angles, right, straight, obtuse, acute, and linear pair. Use this in middle school when students are learning the meaning of these words or in high school Geometry as a review. When I do this with my students, I make it a race...the first group to have their strips cut and correctly organize wins a prize :)
*I also have a WORD version available ($10) in which you can edit to meet your needs. Change terms, descriptions, and pictures to cover the exact content you are doing in your own class.
