This is an easy common core type thinking activity designed to get your student to understand that points are solutions. Students will be working cooperatively in GROUPS of four to sort points to FOUR DIFFERENT standard form equations. Once sorted, students will glue and graph the points.

***Includes pre-activity warm-up.***
***Includes cut and paste materials for groups of four students***
***Includes post-activity homework assignment.***

This activity targets so many of the concepts that students struggle with:
* The idea that points are solutions.
* The idea that a line shows the solutions to the function rule.
* The idea that if a point is not part of a solution set it will be "out of line" and that graphing is a way to verify if points are part of the solution set.
* The idea that a function rule has more than one solution.
* The idea that a point can be verified algebraically even in standard form.
* The idea that even if a point's values are too large to graph, it is
still part of the solution set.

This activity makes an amazing observation lesson. (Of course, you should run through it once before with a different class, before you try it in front of your administrator).

You could also shrink this down a bit and have students use this as part of their interactive notebooks. (Each student gets a different page). Or you could use this as a math center activity, and leave the answer key in a folder.

Key words: Graphing linear equations, plotting points, solving linear equations, verifying points on a line, verifying if a point lies on a line, verifying solutions, linear functions.
