Algebra 1 - FLEX Class 4: Solving Systems of Equations

ATTENTION: Due to multiple requests, I have created the following placement test for my Algebra 1 classes:
Placement Test and Answer Key: https://drive.google.com/drive/folders/1w3eQh0SdxQy7YiDFTAkHDJxniS07Tf0v?usp=sharing

In this class, students will learn:

Week 1: Solving a System of Equations by Graphing
Week 2: Solving a System of Equations by Substitution
Week 3: Solving a System of Equations by Elimination 
Week 4: Graphing Systems of Inequalities

A video will be posted at the beginning of each week.  Students should have paper and pencil while watching the videos as time will be added within the video to complete practice problems. 

A discussion question will be posted in the classroom each week and students will be encouraged to join in the discussion by answering the question(s) and replying to other students.  I will also be participating in the discussion. Math articles may also be used occasionally to facilitate class discussions.

In addition to homework problems, a quiz will be provided each week which students can turn in for grading and feedback. A picture of the quiz can be sent to me by uploading it to my Dropbox folder through the link I will give you. You do not have to have a Dropbox account to upload the homework to my folder. 

I use the gradual release method of teaching: " I do, we do, you do" 
- First, I demonstrate how to do it (using several examples).  
- Next, the students do some problems along with me.
- Finally, they are provided with one problem at a time to complete on their own before watching me demonstrate how to solve the problem.

I believe repetition is the key to learning Algebra, so we do many problems together during each session (through the video).  Then, when I ask them to do a problem on their own (again, through the video), I  go over it afterward, so they can see any errors they may have made.  I find that this reduces any anxiety some students have about math.

Practice homework will be provided along with a full answer key for checking the answers.  However, there will be no answer key provided for the quizzes since I will be grading them to offer feedback. I always include every step in my answer keys so students and parents can see where any errors were made.
