In Module 4, students extend what they already know about unit rates and proportional relationships to linear equations and their graphs. Students understand the connections between proportional relationships, lines, and linear equations in this module. Also, students learn to apply the skills they acquired in Grades 6 and 7 with respect to symbolic notation and properties of equality to transcribe and solve equations in one variable and then in two variables.

Graphing Linear EquationsMathematics Instructional Plans (MIPs) help teachers align instruction with the Mathematics Standards of Learning (SOL) by providing examples of how the knowledge, skills and processes found in the SOL and curriculum framework can be presented to students in the classroom.

This task requires students to use the fact that on the graph of the linear function h(x)=ax+b, the y-coordinate increases by a when x increases by one. Specific values for a and b were left out intentionally to encourage students to use the above fact as opposed to computing the point of intersection, (p,q), and then computing respective function values to answer the question. The Virginia Department of Education resource titled, "Graphing Linear Functions," which requires students to graph equations in y=mx + b form includes a template and lesson plan.

Students will find helpful resources for learning and practicing math skills and processes in this eMediaVA collection.

This collection has resources organized by grade level teachers can use to teach math.

Students use their problem solving skills to determine how many months a tenant can pay rent from a certain account. While the problem only has one solution, there are multiple strategies that can be applied to solve the task. The teacher should monitor solution strategies and purposefully select and order how students will share. A teacher guide is provided.
