Here's the answer, the winner of the contest for
the closest guess is Allison H. She guessed 425 and the answer was, well
watch the video to find out. :)
The interesting thing about the guesses is that
almost no one guessed a number that didn't end in 0 or 5. I hope they just
thought I was using only exact rolls and went from there. However, I did
not, I filled it up. Many, many guesses of 400.
Awesome job, they explained to me in class today
that the reason they chose 400 ranged from estimating, figuring out the ratio,
measuring, and even setting up a formula where "x" was the variable
for space left in the jar.
My goal was to get them to think and explain math
in their own terms without a book problem, but with a video example.
I think it worked! :)
Conferences are tonight and also Tuesday, hope to see you there!
