Why teach Multiplication 10s, 11s, 12s facts?
This teaches the 10s, 11s, and 12s multiplication facts, e.g., 10 x 7, 11 x 4, 12 x 6. This Learning Track is optional. Can be used by those students who have mastered the 0 through 9s Rocket Math multiplication facts. Especially helpful for students who complete the 0s through 9s quickly and need something else to work on during “Rocket Math” time. These facts are not critical to be able to do multi-step multiplication, but they are useful to know by memory. The tens and elevens mostly follow a simple rule and aren’t hard to memorize. Because there are 12 inches in a foot, it is helpful to know multiples of twelve, especially when measuring. Finally, this is an excellent review because it includes cumulative review of the 0-9s facts while gradually teaching the 10s, 11s, and 12s facts.
How does the Learning Track work?
This Learning Track includes the same Rocket Math process, worksheets, and routines. The sequence of facts learned in Multiplication 10s, 11s, and 12s can be seen above.
