# Unit #2.Lesson #1.Equations and Their Solutions

In this lesson we make sure that students understand the basic concept of what a solution to an equation is in terms of truth values. This is emphasized up front, as opposed to bringing in checks at the end. I like this approach because I want students to understand the forest of equations before we start wading through the trees.

And here is the video:

1. Has anyone introduced the concept of a solution graphically? The students should already be familiar with the basics of graphing a line and I was wondering if it would be appropriate to remind them that the solution to the equation of a line is a point on the line. I’m conflicted wondering if introducing the graphing concepts would be too much at this point but at the same time thinking that this lesson might be too simplistic.

2. Scott,

Have you looked at the lesson called “The Truth About Graphing.” It is Unit #4.Lesson #10, so it is a ways off, to put it mildly. But, it really its on this crucial, and often misunderstood, idea.
