Of course, I can't find the activity sheet online that I used for this activity but basically I had my Accelerated Algebra I students bring in pennies. It is a small class, but we collected a bunch. Then, we worked as a class to sort them and it ended up making its nice own little histogram. Next, we made a box and whisker out of the dates of the pennies.
Here is the class busy at work: (the pennies are so little, they are hard to see) Can you tell where the pennies from the 2000s are?
