We have been working hard on learning and practicing the *process* of multiplying up to 4 digits by 1 digit and 2 digits by 2 digits. Just learning how to use the “old school” algorithm to solve the problem is no longer enough. The kids have to be able to *explain the process* of why that “old school” algorithm works. I’ve posted short video clips that help to show the multiplication process and what we are expecting the kids to understand and do. Of course, it is **extremely important** that the kids learn and **memorize** their basic multiplication facts!
