Reflection: Discourse and Questioning Dog Pen Problem Solving - Section 3: Student Practice


During this lesson, I found a couple of students counting by two to find the number of "twos" in 86. In this video, you'll see me guiding the students as they discover a more efficient strategy: Finding Efficient Strategies

I think it's interesting how some students fall back on their "old strategies" like counting instead of using new more efficient strategies. 

I look forward to checking on these two students during future problem solving to see which strategies they are using.
