We did a traditional left side of the page thinking for the output, but for the proof/application, I wanted to work together to solve for mean, mode, median, and range, using the definitions we came up with. We collected a quick set of data (I asked them how many markers they had in their desk) to work with, and got to work. It was a perfect way to introduce these concepts to them.
The next day we continued with our study of mean, mode, median, and range with a special OREO day. :) This is one of my absolute favourite days of the year ... cookies and math ... can't beat it! In fact, my own daughters wanted to get in on the action the night before ... how could I say no? If you want to read more about our Oreo Stacking Challenge, it's in my original Interactive Math Journal, and I have a blog post you can read more at HERE.
