What This Standard Means
What Students Need to Do
- Students move between graphs, tables, equations, and written descriptions of the same proportional relationship. They identify the constant of proportionality and use it to keep each representation consistent.
What Mastery Looks Like
- A student can find the constant of proportionality from a graph, table, equation, or description. The student creates matching forms, labels variables, and explains what the constant means.
Common Misconceptions
- Students may use y = x + b instead of y = kx, or assume every straight-line graph is proportional. They may reverse the variables, use inconsistent ratios, or omit the origin when making a graph or table.
How to Assess It
- Show a graph passing through (0, 0) and (4, 10). Ask students to write an equation, make a three-row table, and describe the relationship in words.

Ways to Teach It
Give pairs ratio cards, graph cards, tables, and equations, then have them build matching sets and explain the constant of proportionality.
Show the table x: 1, 2, 4 and y: 3, 6, 12, then ask students to write and defend the equation.
Play a translation relay where teams convert a card into a table, equation, and sentence before checking with an answer key.
Use a grocery unit-price sign to create a cost table, write an equation, and describe how total cost depends on quantity.
