Common Core Math Grade 8 Represent Proportional Relationships

In Grade 6, students were introduced to ratios and unit rate. They learned to use ratio reasoning to solve problems.
Proportional relationships were a major focus in Grade 7. Students learned to compute unit rates that included fractions as well as determine if a relationship is proportional. They represented proportional relationships in graphs, equations, tables, diagrams, and verbal descriptions.
In this lesson, students will extend their understanding of proportional relationships to discover that they are one kind of linear function.
