Florida B.E.S.T. MA.6.AR.1

MA.6.AR.1 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.6.AR.1.1

  Given a mathematical or real-world context, translate written descriptions into algebraic expressions and translate algebraic expressions into written descripti...

• MA.6.AR.1.2

  Translate a real-world written description into an algebraic inequality in the form of x > a, x < a, x ≥ a or x ≤ a. Represent the inequality on a number line.

• MA.6.AR.1.3

  Evaluate algebraic expressions using substitution and order of operations.

• MA.6.AR.1.4

  Apply the properties of operations to generate equivalent algebraic expressions with integer coefficients.

01

What Students Need to Do

Students use what they know about numerical expressions to read, write, evaluate, and rewrite expressions containing variables. They connect words, models, and symbols while applying operation rules and properties.

02

What Mastery Looks Like

Students translate phrases into algebraic expressions and identify terms, coefficients, constants, and variables. They correctly substitute values, follow the order of operations, and use properties to rewrite expressions.

03

Common Misconceptions

Students may read 3x as 3 + x or think a variable always has one fixed value. They may combine unlike terms or ignore the order of operations when substituting values.

04

How to Assess It

Give the exit ticket: “Evaluate 4x + 3 when x = 5, then explain what 4x means.”

1. 01

   Give pairs variable tiles and unit tiles to build 3x + 4, then match the model to an expression.

2. 02

   Ask students to write and explain an expression for “five less than twice a number.”

3. 03

   Play expression match with cards showing verbal phrases, algebraic expressions, tile models, and values after substitution.

4. 04

   Use a phone plan with a monthly fee and per-gigabyte charge to write and evaluate an expression for different data use.

• MA.912.AR.1

  Interpret and rewrite algebraic expressions and equations in equivalent forms.

• MA.912.AR.1.9

  Apply previous understanding of rational number operations to add, subtract, multiply and divide rational algebraic expressions.
