This hands-on activity is great to use for a small group, for math centers, stations, or whole group instruction. This is for lessons on Similar Triangles. Specifically, it is about solving missing sides of proportional parts of right triangles. This is also known as Geometric Mean.

This product has two options.

Option 1 is a math relay. The students will create a maze by will solving missing sides of proportional parts of right triangles. There are 12 cards with diagrams on solving for missing sides. Each card has shaded squares that have the answers and unshaded squares which have the questions. Students can start with any card. He or she will solve the question attached to it. She then finds the card that has that answer and connects it to his/her card. Repeat the process until there is no more card left. The answer to the last card is on the first card. Your students will enjoy putting together the puzzle as they solve math problems. In a group, students work together to match their problems and answers and solve the puzzle. If they solve the problem correctly, they find the answer piece and continue working, but if they don’t, they must recheck their work and correct the mistake before they can move on. Also, the puzzle pieces are jumbled so you can have students cut them out without seeing the answers.

Option 2 is independent classwork. This product also includes a worksheet that has the same questions as the puzzle but in a different order, so you can use it as make-up work for absent students. All the keys are included.

I hope you enjoy this activity. Please leave a comment below.
