## Reflection: Checks for Understanding Mowing Lawns - Section 3: Student Practice

While checking for understanding, I found that many students struggled with explaining the zero in the one's place. When looking back on this lesson, I could have also included an activity within the main lesson to help students develop an thorough explanation. For example, we could have compared problems, such as 6 x 15 and 60 x 15. When further analyzing 60 x 15, we could have decomposed the 60 x 15 into 6 x 15 x 10.

Here are two conferences in which I try to guide the students to a deeper understanding.

#2: 30 = 3 x 10
