Standard(s) Taught

MAFS.7.RP.1.1

Compute unit rates associated with ratios of fractions, including ratios of lengths, areas and other quantities measured in like or different units.

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.

  4. Explain what a point (x, y) on the 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.

MAFS.7.RP.1.3

Use proportional relationships to solve multistep ratio and percent problems.

Learning Targets and Learning Criteria

Students are successful when they can…

  • compute a unit rate by iterating (repeating) or partitioning given rate.
  • compute a unit rate by multiplying or dividing both quantities by the same factor.
  • explain the relationship between using composed units and a multiplicative comparison to express a unit rate.
  • use measures of lengths and areas to calculate unit rates with the given context.
  • 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.
