Our class has recently started working on multiplying and we are coming up with different stratigies to help us understand better.
The process:
1) break the two factors (52 and 39) into two seperate numbers. One ending with a zero.
2) Multiply to get answers in the boxes (post-its)
3) Once you have your products, then add across.
4) The final step is to add your remaining numbers for your final product.
The students find this method easier to do and understand because it breaks down numbers visually.
Hope this helps!
