I have produced a Beta version of a sequence of algebra 1 videos (up to 1 step equations as of Aug 15, 2021 with more on the way).
My approach is to unpack the concepts before showing the steps so the student understand how the math works. The videos are kept shorter, when possible, and they build on each other.
I will eventually revise many if not most videos based on feedback. Also, I will create a practice worksheet for each. For now I am simply trying to get something out there for the start of the school year. Solving equations is an incredibly important math topic to master and I hope these help.
I am rolling out a series of videos on math topics from middle school and algebra 1. Here is a link to the folder with the accompanying handouts. This post will be updated periodically.
Let me know if your school is covering a topic that is challenging and students would benefit from an alternative presentation. I will see what I can do. The links to the videos are listed below the photo.
First I develop an understanding of a balanced equation vis-a-vis an unbalance equation using the seesaw representation.
I then explain that the same number of guys must be removed from both sides to keep the seesaw balanced.
I then apply the subtraction shown above to show how the box (containing an unknown number of guys) is isolated. I explain that the isolated box represents a solution and that getting the box by itself is called solving.
I use a scaffolded handout to flesh out the “mathy” steps. This would be followed by a regular worksheet.
I extend the solving method using division when there are multiple boxes. I introduce the division by explaining how dividing a Snickers bar results in 2 equal parts. When the boxes are divided I explain both boxes have the same number of guys.
The students are then provided a scaffolded handout followed by a regular worksheet.
