There's no way that's a fair comparison! Why didn't you compare the first workbook to the "Penny Jars and Plant Growth" section of SM!!!

Katharine Beals said...

Because SM doesn't have a "Penny Jars and Plant Growth" section.


The first workbook doesn't have graphing problems.

The two problem sets come, respectively, from the ultimate and penultimate chapters of IM and SM.

In what way is this not a fair comparison?

(Or are you being ironic, Auntie Ann?)
