We also did a great activity with styrofoam cups. Our objective was to find out "how many styrofoam cups stacked will it take to reach the top of Mrs. Adams' head". To trick the students, I measured in centimeters, otherwise it would have been too easy. We found out it took about 86 cups. I was amazed to see the thinking process from all of the students and was quite impressed! We used a circle map to help organize our thoughts and solving process and the students went right to work.
Do you want the cups stacked this way?
Let's see the height of two cups stacked together.
A circle map to organize the process.
"See how the cup as a top part or rim?"
So Mrs. Adams didn't buy enough cups so we are adjusting to determine if it really takes 86 cups.
Thanks for a wonderful start to the year!
