Standard(s) Taught 

MAFS.7.RP.1.2
Recognize and represent proportional relationships between quantities.

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 (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.

Learning Targets and Learning Criteria 

Students are successful when they can…
 analyze ratios in a table to determine if the ratios are equivalent by find 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
 calculate the constant of proportionality/ unit rate given a verbal description of a proportional relationship.
 compute the rate of change/ slope from a graph or equation (k in y=kx)
 sole equations created from proportional relationships
 write an equation from a proportional relationship
 calculate the unit rate by identifying that on a graph when the xcoordinate is 1, the ycoordinate is the unit rate
 define the rate of proportionality from a graph
 explain that the ycoordinate divided by the xcoordinate for every point other than the origin equals the constant of proportionality.
 explain the meaning of a point on a graph y=kx of a real life situation.
