Teacher Notes If you want to make a class set, I

would recommend laminating the

cheat sheet so that you can use it

year after year.

You could also decide to print a

cheat sheet for each student and

have them glue it into their

interactive notebooks.

If you give one to each student, you

could have them color the cheat

sheet (If time is limited, I would skip

or have students color at home).

Please let me know if you have any

questions about the cheat sheet!

You can email me at

[email protected].
