Pennies in Circulation
The goal of this project is to determine what year pennies are in
circulation. Using 100 pennies, we will tally the dates.
~ Our Work for the Project~
 We began by bringing in 100 pennies
from home. Once we had our 100-penny sampling, we were ready to begin our
work.
 We first discussed the term
"circulation", then talked about our guiding question -
what dates would be found on this sampling of 100 pennies in circulation.
We made predictions as to what would be the "oldest" and
"newest" dates.
 We divided the pennies among the
students. Then using a strip with 5 boxes, we wrote the dates of the
pennies in the boxes and cut the boxes apart.
 We continued our work by creating
picture graphs, writing about the project in Writers' Workshop, and using
number strings to find out how many pennies we had from each decade. We
also learned some penny facts. For example, did you know that all pennies
that are in circulation are either minted in Denver or Philadelphia?
