This is a 100% original idea I thought up to help students in naming angles. This activity forces students to think about naming angles with three letters, and think about the relationships between vertical, complementary, and supplementary angles. I give a detailed tutorial on how to create a manipulative that students can use individually, in pairs, or in small groups. I included designs to go with the manipulative, questions, and answer key. The only materials required are construction paper and brackets, the rest is printable.
