Print on cardstock and cut into cards. Set contains 24 questions for teacher use and 24 answer cards for students. Deal out answer cards (either deal same # to all students, or give brighter students an extra card to challenge them more); students put them face up on their desks. Teacher asks question. 1st student with correct card must then answer in a complete sentence; when done, turn that card over. First student to turn all cards over wins.
