This week we began learning multiplication. I introduced it by explaining arrays and repeated addition. As I progressed throughout the week reviewing these two strategies with my students I learned something new myself. I realized that I was teaching them in a way I never had before. In repeated addition the multiplication fact 4x3 is written as 4+4+4. I found myself telling students "You just write 4 three times. That is why we say 4x3. I guess I have always know this, but I have not always thought to explain it this way. I think that far more children understood it when I explained it this way. We also started on our 0, 1, and 2 facts this week. I noticed many of my students using the repeated addition and arrays to help them with the facts they didn't know. Do any of you have tricks of the trade that I can use?
