1. Reviewing Systems of Equation by: Karla Goldhahn Instructions: 1.Print/open the Reflection sheet (click on link). You will need to answer questions as you go through the presentation.Reflection sheet 2.Go through each slide, in order, watching the videos, answering questions, and following other directions as you go.

2. Remember that, by definition, a “solution” to a system is… http://www.mathplanet.com/education/pre-algebra/graphing-and- functions/solve-systems-of-equations-by-graphing http://www.mathplanet.com/education/pre-algebra/graphing-and- functions/solve-systems-of-equations-by-graphing Reflection: 1.What is a “system of equations”? 2.In your own words, what does it mean if something is a “solution” to a system of equations? 3.If you have a system of three equations, explain what the “solution” is. STOP… did you print out the “Reflection sheet”? If not, click here.click here http://www.virtualnerd.com/algebra-2/linear- systems/equations-solution-definition.php

3. There are a few different ways to find the solution to a system… click here Reflection: 4.What are the three methods for finding the solution to a system of equations? 5. Why do you think we need three different methods for doing the same thing? STOP… open and print this handout to use as you watch the video.this handout

4. Let’s focus on the elimination method… Print this (hint: “linear combination” is synonymous to “the elimination method”) Print this synonymous Watch this Practice this (answers are included so you can check your progress) Practice this

5. Reflection: 6. Find the solution to this system of equations. 7.Explain HOW you found the solution (step-by- step). 8.How can you check to make sure your solution is correct?

6. Submit your “Reflection sheet” to the drop box labeled: Reviewing Systems of Equations. Then, email me a response to the following: Was this presentation helpful for you? What did you like about it? How would you improve it? I, Ms. Goldhahn, will review your responses and consider resetting previous assignments based on the level of understanding you demonstrate in your reflections.
