I’ve spent the morning working to write a new unit on systems of equations. Here’s my progress so far. The unit is currently missing a few skills. Activities for determining the number of solutions there are in a system and solving systems of inequalities are not up yet. But I’m done for the moment. The jump off point is unit-systems.pdf, it links to the other files so you can open them right from it. Thanks to Dan Greene for posting his unit on systems of equations from which I adapted but mostly copied the skill list in the unit.
You can peruse the initial lesson below.
The unit plan is here:
Here’s the folder.
You can download the whole folder zipped up. unit-systems.zip.
