These little cards are paint sample cards from Home Depot, Lowes or Wal*Mart. I asked the manager if I could have some and he was very kind. I only took 13 cards so I could do the "sevens" times tables, but once I started making them I wish I had picked up another color. Next time I'm there I'm going to ask for some more colors so that I can do the "sixes" in one color and the "eights" in another color, etc! If you are not familiar with triangular flash cards, they are W.O.N.D.E.R.F.U.L!
Elementary math videos and songs. Try the 9 X 9 song to get a hint of how good these are. His whole site is great for every classroom. Teachers MUST use more music and teaching videos to make the quality of their lessons better. CW
