Lesson unit serves as a formative assessment tool to determine how well students are able to formulate and solve linear equations in two variables. Students work individually and in small cooperative learning groups to build conceptual understanding through the use of a range of mathematical practices.

Materials provide instructional strategies to address common misconceptions.
