If you aren't familiar with poke cards, they are cards that have a problem along with several punched holes and answer choices above them. Students use a pencil to poke the right answer. On the back of the card, the hole punch with the right answer has a circle around it, so students can self-check or partner-check while playing.
I actually checked the students today, and it helped me have an idea of where each student was at with regards to this skill.
A little side note - instead of using pencils, I actually used some plastic flower sticks from a bouquet I had. They are safer than pencils, and students seemed to enjoy using them.
I just posted these 60 cards in English and in Spanish for just $1.
