2-digit multiplication

Barb,
I have a student this year who has lots of problems processing information. He is such a sweet kid and tries his hardest to understand, keep up, and perform. I figured out a way to help him do 2-digit multiplication| just a week or so ago. This what we did. We tried using one color for the digit in the ones place of the multiplier and a different color for the digit in the tens place. We tried to use the same colors when we did the actual multiplying but found it was too confusing to keep trying to remember which colored pencil to pick up each time. So, I set up each problem by drawing boxes |

in 2 different colors for the ones digit and the tens digit of the multiplier, and then also drawing boxes the same colors on the lines where the multiplication was to be done. That way my student could use a regular pencil to do the math while the colored boxes gave him clues about which digit was being used to multiply. Now that's a really wordy way to say: multiplicand
x blue box, red box
red box, red box, red box
blue box, blue box, blue box, blue box-(w/0)
(the sum of the red and blue boxes) I hope that makes some sense. I love ProTeacher but I wish we could use word processing style tools such as spell check, underlining, etc. Elaine
