Reflection: Checks for Understanding Finding Factors for Numbers 41-70 - Section 3: Student Practice


During today's student practice time, all students were able to complete the first row of the Factor Chart C and many students were able to find the factor pairs for several numbers in the second row. Through conferencing and observations, I know that this is not because of a lack of understanding, but lack of time! I am reminded that a thorough completion of a few problems is more important than a quick completion of many. After this lesson, I was so proud of my students for successfully applying both the prime factorization and u-turn methods to more complex numbers. 

Here's a Student Example of Factor Chart C.

Tomorrow, we will begin by completing the last row (61-70) of this chart together.
