## Reflection: Checks for Understanding How Big Is A Mile? - Section 3: Yards to Miles

Today's task was not a simple one, but for the students who used the tens frames, the task was one that they were successful at. For students who wanted to skip the manipulatives, the math was difficult. They became confused with the many numbers they were trying to add. I told students that even if they were doing the math in their heads, they should help their partner use the tens frames and then they would have a way of checking their own accuracy.

Often children who are used to doing things "in their heads" resist writing out the problem,using manipulatives, or explaining their thinking. Students who struggle more, welcome the assistance of manipulatives. The idea is to help those who are used to using their heads, to realize that there are other strategies out there that can help them when they get stuck. Requiring that they check their work by using manipulatives is one way to honor their attempts to do the work mentally, but also to show them the usefulness of manipulatives.

Based on this lesson, I will plan a lesson with several centers next. At each center, students can try to solve problems by using the manipulatives at that center. It will encourage all children to find a method that works for them when they need to go beyond using just their heads to solve the problem.
