What This Standard Means
What Students Need to Do
- Students show their reasoning with equations, labeled visuals, graphs, tables, or written explanations. They connect these forms and explain what their results mean.
What Mastery Looks Like
- Students choose representations that fit the problem and connect them clearly. They label graphs and diagrams, use symbols correctly, and explain how each representation supports their conclusion.
Common Misconceptions
- Students may show calculations without explaining what the numbers mean. They may create a graph or diagram that does not match the equation, or treat different representations as separate answers.
How to Assess It
- Give an exit ticket with the equation y = 3x + 2. Ask students to draw a graph and write two sentences explaining how the equation appears in the graph.

Ways to Teach It
Give pairs tiles to model 2x + 3 = 11, then have them draw the model and write the matching solution steps.
Ask students which representation best explains a proportional relationship, then require evidence from a table, graph, or equation.
Play a matching game where students pair situation cards with corresponding equations, tables, graphs, and written explanations.
