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.

The Pliability of Numbers: Strategies for Working Within Operations
This free packet contains strategies other than the traditional algorithm for addition, subtraction, multiplication, and division. It also examines ways of viewing fractions and basic algebraic equations. This packet is based on ways my students have solved these type of problems at their various levels of understanding. I did not explicitly teach these strategies, but rather, presented them with the opportunity to think about the meaning of these operations through problem solving. These are wa
