## Reflection: Developing a Conceptual Understanding Factors: The U-Turn Method - Section 3: Student Practice

All students were successful at this lesson. Some finished sooner than others. Understandably, students who could readily identify multiplication facts were able to identify the factors quicker than others.

As for developing a conceptual understanding, I wished that I had used the colored tiles or graph paper to further support this student's understanding of factors: U-Turn for 14.mov. Often, the idea of factors "clicks" when students are given a certain number of tiles and asked find all the possible arrays. This is the perfect opportunity for students to see how a 2 x 6 array can be formed using a 12 tiles, which means 2 and 6 are factors. However a perfect array cannot be constructed when placing 12 tiles in rows of 5... which indicates that 5 is not a factor of 12.

Tomorrow, I'll be sure to utilize the color tiles to represent the abstract idea of factors whenever possible!
