The children then suggested adding a second bus to hold another 40 people.
We knew it would be close...the children then suggested cutting apart the remaining ten frames into single units and dividing these equally into the two buses.
We finally had a solution! Each bus would hold 47 people, and that meant that we needed two buses to bring everyone on our field trip!
We reported back to Mrs. Tessier to share our thinking and show her our work. She was so excited that the children had calculated this on their own and promised to order precisely two buses!
I was amazed at the end of this activity. The children were so confident problem solving with such a large number! I know that it was because they were highly motivated and invested in the math problem because it related directly to their lives and was something that was exciting and important. I look forward to finding more authentic math problems to bring to our whole group conversations.
