Put the students in groups of 2 or 3 and issue each group with 2 post-it notes.
Students then cut and assemble the tarsia puzzle, matching the question and answer. If students are really struggling, they are allowed to write a single question on each of the post-it notes and then wait for the teacher to circulate and answer the questions.
After the time is up, issue each group with the answers and have them complete their puzzles.
