I created a set of flashcards to systematically learn the nine’s multiplication facts. These cards are based on the work of John Van De Walle.
This is how I envision the system working
Next, I made a set of cards that teaches students that the product’s tens place digit will be one less than the “other” factor multiplied by nine.
The next pattern is that when you add the two digits in the product the sum will be nine.
Then it practices the two ideas together.
Lastly, no support is given.
Ta Dah…students know their nine multiplication facts.
