Secondary 3 March break review package.
Before you begin, look at the formula sheet and your textbook to remind yourself of the rules you have learned. I
would prefer if you complete your work on graph paper, but if you don’t have any, blank paper is fine. Please do not
use lined paper.
The answers to these problems can be found at the bottom of the sheet. All answers are missing their units and are
not matched to specific questions. The answers are there simply so that you can tell if the answer you have obtained
is on track.
All work should be shown, and all sheets should have your name and group number written on them. This work is
due on the Wednesday upon return from March break. If you are really struggling, please come see Ms. Ward or Ms.
Howard on Monday or Tuesday!
