This is a task from the Illustrative Mathematics website that is one part of a complete illustration of the standard to which it is aligned. Each task has at least one solution and some commentary that addresses important asects of the task and its potential use. Here are the first few lines of the commentary for this task: Serena is starting a new workout routine and wants to keep track of her heart rate to make sure that she is exercising at the optimum level. First she ...

Students lean about proportions, ratios, and unit rate. It is important for connections to be made among ratio tables, graphing points, and slope of a line. Students make these connections through the first activity provided by the VDOE. The second task by Illustrative Mathematics is a way to assess student understanding.

Students compare slope as it relates to distance vs. time. Using a simulation on Desmos, students find that faster speeds create steeper slopes on a graph.

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.

This lesson integrates computer science through discovering graphing on a coordinate plane for 6th graders all the way to a review for 8th graders with extensions that include slope.

In this task, we are given the graph of two lines including the coordinates of the intersection point and the coordinates of the two vertical intercepts, and are asked for the corresponding equations of the lines. It is a very straightforward task that connects graphs and equations and solutions and intersection points. The students will use a VDOE resource to recognize and describe the graph of a linear function (foldables, bingo game, lesson plan for the teacher).

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.

In the Racing Away lab, students will understand the physical meaning of slope as a rate of change and the y-intercept in distance vs. time plots. Students will also come to understand the meaning of each part of writing a linear equation in two variables in slope-intercept form.

In this lab, students will determine the slope of a line when given two points on the line; write the equation of a line when given the graph of the line, two points on the line, or the slope and a point on the line; and graph linear equations in two variables. Throughout the lab, students make connections between and among multiple representations of functions using verbal descriptions, tables, equations, and graphs.

Recognize and describe the graph of a linear function.Mathematics 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.

In this Desmos activity, students practice defining slope and y-intercept given a real world scenario. Students complete a table and write an equation in the form of y=mx+b for multiple similar situations.

In this task, we are given the graph of two lines including the coordinates of the intersection point and the coordinates of the two vertical intercepts, and are asked for the corresponding equations of the lines. It is a very straightforward task that connects graphs and equations and solutions and intersection points.
