This cooperative learning activity provides students with practice writing linear equations given various pieces of information. Topics covered include:
1) Writing the equation of a line given two points
2) Writing the equation of parallel and perpendicular lines
3) Rearranging from standard to slope intercept form
4) Rearranging from point slope to slope intercept form
5) Writing the equation of a line from a table
6) Writing the equation of a line from a graph
In groups of 4 (2 or 3 if necessary), each student individually solves a problem (various levels of problems are included) and then group's individual answers are summed to come up with a group answer, which is checked with the teacher.
My students get really competitive with this activity, but the nice part is it's not a race--it is better to get each round correct the first time than it is to rush and finish first with some mistakes. This activity naturally builds in skills like checking each other's work, communication, and collaboration.
