Florida B.E.S.T. MA.6.AR.2

MA.6.AR.2 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.6.AR.2.1

  Given an equation or inequality and a specified set of integer values, determine which values make the equation or inequality true or false.

• MA.6.AR.2.2

  Write and solve one-step equations in one variable within a mathematical or real-world context using addition and subtraction, where all terms and solutions are...

• MA.6.AR.2.3

  Write and solve one-step equations in one variable within a mathematical or real-world context using multiplication and division, where all terms and solutions ...

• MA.6.AR.2.4

  Determine the unknown decimal or fraction in an equation involving any of the four operations, relating three numbers, with the unknown in any position.

01

What Students Need to Do

Students translate simple situations into equations with one unknown. They isolate the variable with inverse operations and check solutions by substitution. They distinguish an equation with an exact solution from an inequality describing a range of values.

02

What Mastery Looks Like

A student can solve addition, subtraction, multiplication, and division equations by keeping both sides balanced. The student can substitute the solution to verify it and explain each step. The student can also tell whether a statement is an equation or an inequality.

03

Common Misconceptions

Students may perform an inverse operation on only one side or use the wrong inverse operation. They may treat the equal sign as a signal to calculate rather than a balance. They may also confuse one exact solution with the range of values described by an inequality.

How to Assess It

Use this exit ticket: “Six equal packs contain 42 markers. Write an equation, solve for the number in each pack, and check your answer.”

1. 01

   Model equations on a balance mat using cups for variables and counters for constants, then remove or divide items equally on both sides.

2. 02

   Ask students to explain in writing why subtracting 5 from only one side changes the solution to x + 5 = 12.

3. 03

   Create card sets with situations, equations, operation steps, and solutions, then have pairs race to build correct four-card matches.

4. 04

   Have students write and solve an equation for splitting a restaurant bill equally among friends after adding a fixed tip.

• MA.7.AR.2.1

  Write and solve one-step inequalities in one variable within a mathematical context and represent solutions algebraically or graphically.

• MA.7.AR.2

  Write and solve equations and inequalities in one variable.

• MA.8.AR.2

  Solve multi-step one-variable equations and inequalities.
