This is a set of 3 thumbs-up /down student response cards (3.75” x 4.5”) you can use as a formative assessment to judge student understanding and help guide your instruction. They can also be used during practice time to help you determine which students need immediate help as well as which students might act as a peer tutor.
I have bundled multiple sets of student response cards, a poster set, and blank exit tickets (Fun Student Self-Assessment: Bundle!) at a discounted price. Check it out in my store!
