## Reflection: Intervention and Extension Law of Cosines Day 2 of 2 - Section 2: Solving triangles when 3 sides are known.

When I differentiate instruction, I like to work with one or two students. I work with small groups so that I can ask students questions and learn more about when and how they are misunderstanding problems that are difficult for them. As discussed in prior lessons, in lessons like today's, I often model reading skills, to help students identify and use information in a contextual problem. I did a lot of 1-on-1 reading work with today's lesson. I also noticed that students were helping each other with reading and interpreting the problems.
