Background:Strong mathematics students are able to see more than one way to solve a problem. Solving even the simplest of equations can be done in various ways and most people develop their own order in which they perform various steps. For example, some will want to manipulate the numbers so that the variable is on the left side right from the beginning while others might like to avoid negative numbers. These preferences will change the look of the answer.The goal of this lesson is to create a situation where the student must follow and narrate someone else's solution to a problem. They will then create their own solutions to a series of word problems.

Instructions for Students

1. Each of the following pages contains a an algebraic equation or expression which has been solved or simplified. Some are videos and some are written directly on the page.

2. Watch the video (or read the solution) as many times as you need to in order to get an idea of the details of what was done in each step of the solution.

3. Once you are ready, you will narrate (record your voice) each step of the solution while the video runs. Be as clear and concise as possible and feel free to record as many times as possible until you are satisfied with the result.

Note: The instructions may differ slightly for each question so be sure to read carefully. In some cases you may also write directly on the question and it will be recorded.

Question #4b

Solve for x:

2(x+5)-3(x+1) = -3x+152x+10-3x-3 = -3x+15

-x+7=-3x+157=-2x+15

-8=-2x4=2x2=xx=2
