Ch 2: Connections with Proportions, Lines & Equations: CCSS.Math.Content.8.EE.B

About This Chapter

Share this chapter's lessons to reinforce classroom instruction on proportions, lines and equations. Use the quizzes that follow each lesson to test your students' progress.

Standard: Understand the connections between proportional relationships, lines, and linear equations.

About This Chapter

Students who have mastered this standard are able to graph proportional relationships and interpret unit rates as the slopes of graphs. They are also proficient in comparing proportional relationships represented in various ways.

Lessons in this standard cover concepts such as:

  • Tips for finding and applying the slope of a line
  • Strategies for determining and using a line's intercepts
  • Understanding how to rearrange equations in slope-intercept form

Students demonstrate mastery of this standard when they solve proportional relationship graphing problems. They also are able to explain the concepts of slope and intercepts of lines in classroom discussions. College and career readiness is supported by students' command of this standard because being able to use visual representations of mathematical functions can help them learn and retain information more effectively.

How to Use These Lessons in Your Classroom

Here are some strategies for using these lessons to support instruction in the CCSS.Math.Content.8.EE.B standard:

Writing in Math Lessons

Upon watching a video lesson and successfully completing practice exercises, ask students to write the solutions to several problems in sentence form.

Social Studies in Math Lessons

Display a large map, asking students to locate spots where specified roads or highways intercept. Ask students to compare and contrast this practice to the concept of x- and y- intercepts in mathematics.

Math Equation Lessons

After sharing the lesson pertaining to finding the slope of a line, challenge students to complete additional slope exercises in which they have equations of lines available, as opposed to knowing two points. Ask successful students to share verbally their solutions with the class or small groups.
