For this activity you will need to have access to a set of overhead tangrams and sets of tangrams for each of your students. If you don't have enough sets for each student, give them a reproducible with the tangram shapes and have them cut it out. Make a shape out of your tangram pieces and display it on the overhead. Have students replicate the pattern using their own pieces to learn at first. If you have previously introduced tangrams to your class, place an outline of the shapes on the overhead and let them figure out how to put the pieces together. You might want to trace these ahead of time and have them available for when you have extra time.
