This product is also listed as "Introduction to Algebra."
This short PPT explains (in a slightly silly way) that the "mystery box" problems that students learn to solve during their early years in school are really algebra problems. The PPT explains what algebra is and why mathematicians use letters for variables. The PPT is visually appealing in order to keep students engaged long enough to deliver the necessary information in the lesson.
I hope you'll like the lesson. It's short, sweet, and to the point. Thanks for your interest.
