9's Multiplication Anchor Chart

Last year I taught my students the 9's "finger trick"
This summer my husband taught me about rounding to ten- multiplying the other factor and then subtracting by the second factor. 
Another nifty observation made by a friend: Factors 1-10 have products that add to nine :D
Math is so cool!!!
