Don't be an airhead
Task 1 - Estimate! How many mini airheads are in the bag?
The pictures of the bites are to actual size!
Calculate how much you would expect, given the label!

What do you notice? What do you wonder?
How many airheads did you expect?
Is it close? What is the percentage of error?
Are you mad, bro? ..or satisfied?

Extension!
Like Dan Meyer's Starburst pack, some airheads are just better than others. I had my willing participant try all of the colors and determine which she liked the best. Any predictions? Why? Does the reveal above tell you anything?
The experiment...
Then she ranked them
Now the distribution... what do you notice? What do you wonder?
What do you think of the distribution?
Are you mad? Happy?
