In this unit, students explore what relationships are defined as proportional and how those relationships can be represented in situations, tables, double number lines, graphs, and equations. They create all of those representations for proportional and non-proportional relationships, defining the attributes in each representation that identifies the relationship is proportional. They also identify the constant of proportionality in each representation.
Proportionality is the key throughline of Grade 7, including representing proportional relationships using situations, tables, graphs, diagrams, and equations. Students use proportional contexts to understand how these relationships behave when represented in multiple ways. This work builds on Grade 6 understandings of ratio and rate, and is foundational to the rest of Grade 7, Grade 8, and beyond.
Students will build on and apply their learning about proportional relationships in Unit 7.7 Proportional Reasoning.
