Unit 2 Quiz

This week you will have a quiz on Ratios and Rates.  The quiz will consist of 8 questions similar to those that you have seen in your homework packet and during class.

You will need to be able to:

ü Identify equivalent ratios

ü Complete ratio tables

ü Use proportions to problem solve

ü Go from a part to part ratio to a part to whole ratio

ü Calculate unit rate/unit price

ü Determine the better buy

   Use the Distributive Property to create two equivalent expressions AND explain the terms in the expression (YES, a throwback to Unit 1!)

   There are a couple of links below for Khan Academy videos.

I   If you need help with any of these topics you can come during lunch for extra help on Tuesday (that is 4th period for classes 622 and 623).  If you are in class 624 see me during homeroom.

    You also have access to TenMarks assignments which I will be updating today as well.  These assignments are optional extra practice.

 
Below are a few links to Screencasts (videos of myself problem solving where you can't see me you can only see my work).  The sound was not working on my computer so as soon as I fix that the videos will have sound to go along with the work I am doing.
