Math Anchor chart- Nifty Nine Trick for SIMPLE addition

I made this anchor chart because my students (who are in the third grade now) STILL have trouble and use their FINGERS to compute basic math problems with 9s in the ones digit.  Since it drives me nuts, I decided to throw up an anchor chart and go over it for a couple of weeks 5 min/day to see if they learn the trick!  Good luck!
