## Reflection: Continuous Assessment Double-Digit Subtraction - We Can Do It - Section 3: Ongoing Assessment

I have given students a wide variety of strategies this year to solve double-digit subtraction problems. I know that I could give them just one and they could all memorize the steps and complete the problems. However, my goal is that they understand the process and complete problems in the best way for them. Students learn differently. By providing a wide variety of strategies, I am encouraging students to meet the Common Core goal of being able to explain why addition and subtraction strategies work based on place value understanding. I am also teaching students to choose the appropriate tool (MP5) for solving a problem that they are faced with.
