Florida B.E.S.T. MA.6.AR.3

MA.6.AR.3 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.6.AR.3.1

  Given a real-world context, write and interpret ratios to show the relative sizes of two quantities using appropriate notation: a/b, a to b, or a:b where b ≠ 0.

• MA.6.AR.3.2

  Given a real-world context, determine a rate for a ratio of quantities with different units. Calculate and interpret the corresponding unit rate.

• MA.6.AR.3.3

  Extend previous understanding of fractions and numerical patterns to generate or complete a two- or three-column table to display equivalent part-to-part ratios...

• MA.6.AR.3.4

  Apply ratio relationships to solve mathematical and real-world problems involving percentages using the relationship between two quantities.

• MA.6.AR.3.5

  Solve mathematical and real-world problems involving ratios, rates and unit rates, including comparisons, mixtures, ratios of lengths and conversions within the...

01

What Students Need to Do

Students compare two quantities, write equivalent ratios, and find the amount for one unit. They use tables, diagrams, and equations to solve missing-value and comparison problems.

02

What Mastery Looks Like

Students label both quantities and units, then choose a table, diagram, or equation that fits the problem. They find equivalent ratios and unit rates accurately and explain what each number means.

03

Common Misconceptions

Students may reverse the order of a ratio or compare quantities by subtraction instead of division. They may divide in the wrong order when finding a unit rate. Some use an additive pattern instead of scaling both quantities by the same factor.

04

How to Assess It

Give this exit ticket: “Three notebooks cost $7.50. Find the cost per notebook and the cost of eight notebooks. Show your reasoning.”

1. 01

   Build bags with two red and three blue counters, then make equivalent batches and record each ratio in a table.

2. 02

   Ask, “Which is a better buy: six yogurts for $4.50 or ten for $7.00?” Students defend their choice with unit rates.

3. 03

   Play Ratio Match with cards showing equivalent tables, tape diagrams, equations, and unit rates; students collect matching sets.

4. 04

   Compare grocery shelf labels by calculating price per ounce for three cereal boxes and naming the best value.

• MA.7.AR.3.2

  Apply previous understanding of ratios to solve real-world problems involving proportions.

• MA.7.AR.3.1

  Apply previous understanding of percentages and ratios to solve multi-step real-world percent problems.
