No-Prep! This 5 days/4 ways problem solving approach gives children an opportunity to be successful with the same problem using a variety of organizers and vocabulary. Accuracy, double-checking and flexible math thinking are naturally embedded. On day 5 they choose their own method to solve a similar problem. Teachers simply print out the pages to be used for mini-lessons, small groups, whole class or tutoring. Students solve the problem a different way each day for 4 days allowing plenty of time for class discussion, partner sharing and accuracy checking. On day 5 they solve a similar problem on their own.
