Reflection: Intervention and Extension Finding Factors for Numbers 71-100 - Section 3: Student Practice


For this lesson, I worried most about my students who aren't as fluent with their multiplication facts as others.

To provide support to a couple of my students who struggle with their multiplication facts, I gave each of them a calculator as a tool to check for factors. The goal of this lesson is for students to develop an understanding of what a factor is and to be to identify the factors for numbers under 100. I wanted to make this goal more accessible to these two students.

Here, I conferenced with one of them as she eagerly uses the calculator: Calculator Instead of relying on her partner to come up with the answers, she was able to investigate on her own! This was such a great moment!
