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.

Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units.
Decide whether two quantities are in a proportional relationship, e.g., by testing for equivalent ratios in a table or graphing on a coordinate plane and observing whether the graph is a straight line through the origin.
Identify the constant of proportionality (unit rate) in tables, graphs, equations, diagrams, and verbal descriptions of proportional relationships.
Represent proportional relationships by equations.
Explain what a point (?, ?) on the graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, ?) where ? is the unit rate.

I can't access any of the links within the lesson plan... seems like good content. How do I get access to the links? I sent a request to whomever owns them through google drive... but...
