I am moving to third grade next year. Through my work with the current 3rd graders in summer school, I am scared to death of teaching the multiplication facts to my new class. Granted, the kids I am working with are there for remediation, I just want to make sure I do everything right to ensure that the class understands the concept and gets the facts. What are some strategies that are tried and true for teaching the facts? Should I focus on the easy ones first (2s, 5s, 10s) or go in sequential order? How long should I spend on each set? Any other pointers?
