Citrus Elementary School
Vero Beach, FL
We think there are 37,384 symbolic butterflies migrating to Mexico. We
used the clues to answer Challenge Question #10. First we figured out
that a hundred 1foot cubes would fit in a space that measures 120" x
120" x 12". Next, since 400 was the estimate of how many butterflies
could fit in a 1foot cube, not necessarily the exact number, each
student chose a number that rounds to 400 as their guess of how many
butterflies would fit in the cube. Then each student multiplied their
number by 100 to form their estimate of how many butterflies in all.
Then Miss Bailey averaged all the individual estimates to come up with
the estimate for the whole class.
