It helped the kids to understand substitution and it was nice that they could view two steps at a time. The kids seemed to like that about the accordion style. You can take a look at what it looked like below. It takes two pieces of paper to get all of the steps down. Next year, I think I will turn it into a chart. Most likely will be faster to complete. However, if kids are making them all year, then it might be a lot faster. I only started doing this with 8th grade this past trimester.
|The cover says "Steps for Solving Systems of Equations by Substitution"|
|The steps are down the left hand side and then an example is down the right hand side. Next year, I will have 2 examples. One will be like y= 2x-3 and y=5x+9 and the other will be like 3x+2y=10 and 4x-5y=13.|
Here is what that foldable looked like.
|The two columns are labeled "Addition Example" and "Subtraction Example". The steps on the left I made using Creately.|
|The two columns on the chart are labeled " Multiply 1 Equation" and "Multiply 2 Equations". Again, the steps were made using Creately.|
Here are the files for the different foldables that are pictured here.
