Welcome to Geometry with Lenny! 

You will be in this class for the entire semester (Hexters 1-3) completing Geometry C1, C2 and C3

This class will run on good old fashioned paper and pencils. We will also use a laptop for some activities.

We will not have a Google Classroom.

Materials: You will need a binder, dividers, loose leaf paper, pencils, and highlighters (optional)

Synergy is still the go-to to check your grade in the class at any time.
