The ABC’s and 123’s Revisited project is an individual activity that stresses problem solving and critical thinking as applied to variables, inequalities, and solving inequality equations.
To be honest, I usually don’t do a project this unit. It is a pretty short unit and nothing really seems to fit well for project-based learning. I reworked the original ABC’s and 123’s from unit 3. It will be a challenging project, but it may not be worth the time.
