Help with Partial Sums
October 17, 2012 | Posted in: Learning Resources
Hello! Unfortunately, I’m out again today with a really bad back. But the kids are in good hands Mrs. Holzman and Mrs. Deming, and I’m hoping to be back tomorrow. In today’s math lesson, kids learned a new method for addition: the partial sums addition method. This was introduced in third grade. It has the benefit from being very supportive of number sense because it teaches students to add by place value. The traditional method of addition, column addition, is still fine. (This is the typical method that you and I learned in school.) But I stress to students that it is important for them to learn and understand both strategies so they can make an informed decision about which method they prefer for their own use. Here is a tutorial video to help the kids (and perhaps you) with this evening’s homework.
