Reflection: Rigor Problem Solving Division Day 2 - Section 3: Concept Development


As you can see in my reflection video, this lesson went well, although not all students got as much done as I had wanted. I had a few groups only get about halfway through the problem page and about half of the class complete through number 9.  Knowing this helps me adjust my instruction for tomorrows lesson.  Since most students did not complete the last two problems, those two problems will be the focus of tomorrows lesson when students complete a gallery walk activity. 

I think most students are doing a great job at thinking about what the question is asking. Thinking about remainders and making sense of a division situation provided productive struggle for most of my students.  A few students wanted to just "do" the division and write that quotient as their answer. As I circulated around the room and saw this happening occasionally, I was able to have great conversations with those groups and be able to guide their thinking about situations.  One student did get upset when I pointed out that he had not answered the questions.  He had done all the division for each problem, but reported his quotient with remainders as his answer to the problem. When I began questioning him about if his answers made sense, he knew they didn't.  He was frustrated that he had to go back and "think" about what the problem was really asking.  This student is really great with procedures and skills, but has trouble applying those skills.  This is such valuable information for me and in my feedback to him and his parents.
