Algebra I SOL Review Name:
Expressions Module: SOL A.1 & A.4b Date:
Be sure to show all work and turn in your scratch work paper!!!
Everything on this review is a topic we have covered. Please put your best effort into it. Even though it is multiple choice, show your work or jot down notes on how you worked the problems. This way you know what you are doing wrong and when we start really reviewing for the SOL test you will have some examples to jog your memory and remind you that we really did do this once!!!! Good luck and do your best.
