#M3CG Unit 1 Summative Assessment

In addition to the two worksheets given in class, (Part 1 & Part 2), you can find several quizzes to go through on your phone.

The Khan Academy links should always work but the IXL will limit you on how many questions you can go through so if you run out of those, use Khan.
