# Day 3: Balancing Noah’s Ark

Day three was all about working together. Whenever I have used groups in the past, there were always students who were not working, students having side conversations, and students who just did not seem to get along with those in the group. I wanted to do an activity that would model the ideals of good teamwork. Development of the skills required for effective collaboration takes practice. We are so busy trying to hit our content standards, that we don’t always recognize the value of spending time teaching “soft skills” such as communication and teamwork. As a result, these skills are often lacking in many professional working environments.

I decided to use Sara VanDerWerf’s 100 Numbers task. I put the students in groups of four, and gave them 3 minutes for the first round. When the round was finished, I asked each group to tell me how many numbers they had found. I wrote their numbers on the board and we discussed possible ways to improve their speed. I told them that for the next round, they would only have two minutes. As soon as I said it, they all immediately started moving their desks as close as possible and leaning in toward the center of the group, ready for the next challenge.

After the second round, nearly all of the groups had improved. There was even one group that found all 100 numbers! I then had them make three columns on a sheet of paper. In the first column, I wanted them to write down words that describe what an effective group looks like. In the second column, I asked them to describe what an effective group sounds like. And in the third column, they were to describe what an effective group feels like. I let them talk for a few minutes, and then as a class, we had a quick discussion of the qualities of effective group work. I projected a picture of the class that I had taken while they were working. They were quite shocked that they did not even notice me taking pictures. I asked them if the students in the picture looked focused, determined, and engaged. It was clear that they were.

Since we still had about 20 minutes left in class, I told the class that I wanted to try to apply our new group norms to a math problem. I gave each group a copy of Fawn Nguyen’s Noah’s Ark problem and gave them the remainder of the time to work on it in their groups. All of my classes were 100% engaged and focused on the problem. Effective group work looked amazing, sounded amazing, and felt amazing.
