Triangle Inequality Theorem Task Cards set includes 24 task cards focused on the triangle inequality theorem. There is a set with QR Codes and a set with QR Codes (they have the same scenarios). The card scenarios vary in difficulty, allowing for classroom differentiation. An answer sheet (should be copied front and back) and answer key are provided. The blank answer sheet allows for mixing cards. Students can record the card number in the space provided.
To prepare the cards, print them, copy along the dotted lines, and laminate if possible. Store in a container or on a ring. Cards can be used multiple times and last for years!
