Mathematicians in Room 123 had earlier worked in teams to solve this problem. Then they took their thinking deeper!
The next day, they again worked in their teams to analyze how Puzzled Penguin solved the same problem. They compared their work with Puzzled Penguin’s work to determine if he was correct and then to identify the error Puzzled Penguin made.
Finally, students gathered to share their thinking. Take a closer look at their work!
