Florida B.E.S.T. MA.5.FR.2

MA.5.FR.2 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.5.FR.2.1

  Add and subtract fractions with unlike denominators, including mixed numbers and fractions greater than 1, with procedural reliability.

• MA.5.FR.2.2

  Extend previous understanding of multiplication to multiply a fraction by a fraction, including mixed numbers and fractions greater than 1, with procedural reli...

• MA.5.FR.2.3

  When multiplying a given number by a fraction less than 1 or a fraction greater than 1, predict and explain the relative size of the product to the given number...

• MA.5.FR.2.4

  Extend previous understanding of division to explore the division of a unit fraction by a whole number and a whole number by a unit fraction.

01

What Students Need to Do

Students add and subtract fractions and mixed numbers with unlike denominators. They multiply fractions, judge whether products grow or shrink, and interpret division involving unit fractions. They apply these operations in word problems.

02

What Mastery Looks Like

A student finds common denominators, works accurately with mixed numbers, and simplifies results. They multiply fractions and use models or reasoning to explain product size and unit fraction division.

03

Common Misconceptions

Students may add or subtract both numerators and denominators. They may mishandle mixed numbers or forget to simplify. Some assume multiplication always increases a value or reverse the wrong quantity when dividing.

04

How to Assess It

Give an exit ticket: calculate 2 1/3 minus 3/4 and 5/6 times 1 1/2, then draw a model for 3 divided by 1/4.

1. 01

   Give pairs fraction strips to model 2/3 plus 3/4, then have them record equivalent fractions and the sum.

2. 02

   Ask, "Will 6 times 3/4 be greater or less than 6?" Students write a claim and defend it with a model.

3. 03

   Play Fraction Operation Match: students pair expression cards with answer cards, earning a point only after explaining their method.

4. 04

   Use a recipe card for 3/4 cup per batch, then ask students to scale it for 2 1/2 batches.

• MA.5.AR.1

  Solve problems involving the four operations with whole numbers and fractions.

• MA.4.AR.1

  Represent and solve problems involving the four operations with whole numbers and fractions.

• MA.5.AR.1.2

  Solve real-world problems involving the addition, subtraction or multiplication of fractions, including mixed numbers and fractions greater than 1.

• MA.6.NSO.2.3

  Solve multi-step real-world problems involving any of the four operations with positive multi-digit decimals or positive fractions, including mixed numbers.
