For each chapter there is 1-2 Chutes & Ladders printable game boards and also a printable answer key. I arrange students in groups of 4-5 and one student has the answer key and tells the others when they are correct or wrong. If they get it incorrect, I make them go back to their previous space to "earn" their way to the finish. I also make them roll the exact number so that others have a chance to catch up. They can go up ladders if they get one correct on a ladder square and go down ladders if they get one incorrect. Students love it! I give them 8-10 minutes to play.
