CCSS.Math.Content.6.EE.C

CCSS.Math.Content.6.EE.C is a cluster heading. These are the individual standards under it.

• CCSS.Math.Content.6.EE.C.9

  Use variables to represent two quantities in a real-world problem that change in relationship to one another; write an equation to express one quantity, thought...

01

What Students Need to Do

Students identify which quantity is chosen or changed and which quantity responds. They use equations, tables, and graphs to show the relationship and explain what plotted points mean.

02

What Mastery Looks Like

Students can identify both variables in a situation and explain how one changes with the other. They can write an equation, complete a table, graph ordered pairs, and interpret points in context.

03

Common Misconceptions

Students often reverse the independent and dependent variables or place them on the wrong axes. They may plot ordered pairs backward or describe a pattern without connecting it to the equation.

04

How to Assess It

Use this exit ticket: “A dog walker earns $12 per hour. Name both variables, write an equation, make a four-row table, and graph the points.”

1. 01

   Have pairs add scoops of rice to a cup, record total mass after each scoop, then graph scoop count against mass.

2. 02

   Ask students to explain in writing how hours studied might affect quiz scores and which variable belongs on each axis.

3. 03

   Give groups equation, table, graph, and situation cards to match, then require one spoken justification for each completed set.

4. 04

   Track the cost of movie tickets for different group sizes, then write an equation and graph the relationship.
