Suppose You’re A Deer...
Each ______ represents a _________.
Each __________ represents a ________.
To feed yourself, grab bean and place it in your dear.
> 1 bean will cause your deer’s stomach to __________ ... it’s science.
If the Number of Beans in Your Cup After 1 Minute = b, then the following is true:
b < 20 ;
b = 20 ;
20 ≤ b < 40 ;
40 ≤ b < 60 ;

And Now You Need a Graph...
Cue clever graph thing to fall in... <laugh>
Show real graph and give time for individuals to create and plot.
Before you get all your numbers written in pen, write a large 0 (zero) in the bottom left corner of your graph.
Let’s Graph It On!
