Partial Sums Algorithm

This resource was created to supplement the second grade CCSS Everyday Math Series.

I use this handout to introduce the partial sums algorithm to my students’ parents. It includes a look at the process step by step with color-coded support, a video tutorial linked as a QR code, and a few practice problems to complete with the tutorial.

I have also taught this lesson using the flipped classroom model and assigned this resource as homework the night before the lesson.
