Unit of InstructionFocus 3: Ratios and Proportional Relationships
Standard(s) Taught

MAFS.7.RP.1.2

Recognize and represent proportional relationships between quantities.

  1. 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.
  2. Identify the constant of proportionality (unit rate) in tables,graphs, equations, diagrams, and verbal descriptions of proportional relationships.
  3. Represent proportional relationships by equations.  For example, if total cost t is proportional to the number n of items purchased at a constant price p, the relationship between the total cost and the number of items can be expressed as t = pn.
  4. Explain what a point (x, y) on a graph of a proportional relationship means in terms of the situation, with special attention to the points (0, 0) and (1, r) where r is the unit rate.
Learning Targets and Learning Criteria

Students are successful when they can:

  • analyze ratios in a table to determine if the ratios are equivalent by finding the constant of proportionality.
  • calculate the cross product to determine if the two ratios are in proportion (equivalent).
  • graph ratios on a coordinate plane to determine if the ratios are proportional by observing if the graph is a straight line through the origin (y = kx, where k is the slope/ constant of proportionality).
  • calculate the constant of proportionality/ unit rate from a table or diagram.
  • compute the rate of change/ slope from a graph or equation (k in y = kx).
  • solve equations created from proportional relationships.
  • write an equation from a proportional relationship.
  • define the rate of proportionality from a graph.
