CCSS.Math.Content.7.EE.B

CCSS.Math.Content.7.EE.B is a cluster heading. These are the individual standards under it.

• CCSS.Math.Content.7.EE.B.3

  Solve multi-step real-life and mathematical problems posed with positive and negative rational numbers in any form (whole numbers, fractions, and decimals), usi...

• CCSS.Math.Content.7.EE.B.4

  Use variables to represent quantities in a real-world or mathematical problem, and construct simple equations and inequalities to solve problems by reasoning ab...

• CCSS.Math.Content.7.EE.B.4a

  Solve word problems leading to equations of the form px + q = r and p(x + q) = r, where p, q, and r are specific rational numbers. Solve equations of these form...

• CCSS.Math.Content.7.EE.B.4b

01

What Students Need to Do

Students turn word problems into numerical expressions, equations, or inequalities. They solve using rational numbers, then check whether each answer makes sense in the situation.

02

What Mastery Looks Like

Students write and solve multistep equations or inequalities from a situation. They check solutions, graph inequality solutions, and explain what the answer means in context.

03

Common Misconceptions

Students may reverse operations in the wrong order or mishandle negative numbers and distribution. They may treat an inequality like an equation, or reverse the inequality sign at the wrong time.

04

How to Assess It

Give this exit ticket: “A phone plan costs $18 plus $0.06 per text. If the bill must stay under $30, write and solve an inequality.”

1. 01

   Use balance mats and algebra tiles to model 3(x + 2) = 21, then record each inverse operation.

2. 02

   Ask students to explain when an inequality sign reverses and include a numerical example that proves their claim.

3. 03

   Run a card sort matching situation cards with equations, inequalities, solution steps, and graphs.

4. 04

   Give pairs a grocery receipt, coupon, and budget, then have them write and solve an inequality for an extra item.

• CCSS.Math.Content.7.NS.A.3

  Solve real-world and mathematical problems involving the four operations with rational numbers.

• CCSS.Math.Content.8.EE.C.8c

  Solve real-world and mathematical problems leading to two linear equations in two variables.

• CCSS.Math.Content.5.OA.A

  Write and interpret numerical expressions.
