Reflection: Relevance Sets of Things - Section 3: Working In Small Groups


The purpose of this portion of the lesson was to help students to see that repeated addition -which leads to multiplication - can be used to solve real world problems. I presented the students with the idea that I needed to order supplies for next year and because I put markers, crayons, and pencils into bins, I needed to know how many of each I had, not how many boxes and I wanted their help to figure it out. The students were excited by the idea of figuring out a problem for me. I told them that we couldn't just open the boxes to see how many were inside, but that on the outside of the box was a number of objects inside.

I handed out the materials, reviewed instructions and let each group go off to work. By the time I had passed out materials to every group, and started to check in on the first group, they were done. They had boxes with 8 markers each. They had written 8+ 8 + 8 = and then counted up and wrote 24. This group of students was done in seconds. 

I circulated around the room and realized that other groups were done as quickly. I thought that the problem would be harder, but the students quickly grasped what they needed to do, and figured out how to solve the problem.  I was delighted that they were able to grasp the concept so quickly and I was able to move on and close the lesson more quickly than I had imagined.

Sets of Things

Unit 16: Getting Ready to Multiply
Lesson 6 of 6

Objective: SWBAT create equal sets of objects and then use repeated addition to explain how many in all.

Big Idea: Multiplication sounds cool to second graders, but we have to know what it is first. Creating and counting sets is one way to get there
