Sub-goal A: Develop automaticity for multiplication and division with 2s and 10s

Multiplication and division with 2s and 10s is an attainable early goal for most students. Using 2 as a factor links to knowledge for doubles and using 10 as a factor relates to base-10 knowledge. These facts become important reference points for learning other facts. The instructional resources provide opportunities to develop fluency with these basic facts.
