A tactile way to verify trig identities! Great for students just starting this process as a scaffolding step before they write out the verifications all on their own. They are given all the steps; they need to arrange them in order and justify/explain them.
This PDF file contains 4 sets of puzzle pieces, 4 answer charts for students to fill in their responses, an answer key, and a link to an editable Google Doc version in case you would like to modify the file in any way.
My students did really well working on this in partners.
