We are going to be doing a lot of data collection and data representation this year.  How cool is that?

I got this idea from one of my fellow teachers at the Mickelson ExxonMobil Teachers Academy this summer.

We go through a LOT of tissues in a school year.  I wondered, exactly how many boxes DO we go through?

As we began discussing the possibilities, it became apparent that figuring out how many TISSUES we go through would be a lot more interesting to think about than just how many boxes we use up.

• We would only count one at a time if we did boxes
• Tissue boxes contain vastly different amounts of tissues (it’s VARIABLE).

So we made predictions about how many tissues we will go through during the year.  We used our background knowledge to make our predictions.

After we made our predictions, we talked about some other kinds of variables (like how we may use more tissues during the winter season due to colds and flu).

We will revisit our predictions several times this year.  We will also keep a running tally of the actual number of tissues used, and see how our predictions measure up!
