Florida B.E.S.T. MA.4.FR.2

MA.4.FR.2 is a B.E.S.T. standard. These are the benchmarks under it.

• MA.4.FR.2.1

  Decompose a fraction, including mixed numbers and fractions greater than one, into a sum of fractions with the same denominator in multiple ways. Demonstrate ea...

• MA.4.FR.2.2

  Add and subtract fractions with like denominators, including mixed numbers and fractions greater than one, with procedural reliability.

• MA.4.FR.2.3

  Explore the addition of a fraction with denominator of 10 to a fraction with denominator of 100 using equivalent fractions.

• MA.4.FR.2.4

  Extend previous understanding of multiplication to explore the multiplication of a fraction by a whole number or a whole number by a fraction.

01

What Students Need to Do

Students decompose fractions and add or subtract fractions and mixed numbers with like denominators. They rename tenths as hundredths when combining those units. They model a whole number times a fraction as equal groups or repeated addition.

02

What Mastery Looks Like

A student can solve fraction equations using models and symbols. They can regroup mixed numbers, rename tenths as hundredths, and explain multiplication as equal fraction groups. Their answers are reasonable and simplified when appropriate.

03

Common Misconceptions

Students may add or subtract denominators instead of keeping equal-sized units. They may treat 3 × 2/5 as 3/5 or 6/15. Some forget to regroup a mixed number or that 3/10 equals 30/100.

04

How to Assess It

Give this exit ticket: solve 7/8 − 3/8, 2 1/4 + 1 2/4, 3/10 + 25/100, and 4 × 2/5. Require a model for one problem.

1. 01

   Have students use fraction strips to build, combine, and remove fractions, then record each model as an equation.

2. 02

   Ask, "Why does the denominator stay the same when adding fourths?" Have students answer with a drawing and two sentences.

3. 03

   Play a matching game with cards showing fraction models, operation equations, and answers, including mixed numbers and whole-number products.

4. 04

   Use a recipe card to calculate ingredient amounts for two, three, or four batches using fraction multiplication.

• MA.4.AR.1.2

  Solve real-world problems involving addition and subtraction of fractions with like denominators, including mixed numbers and fractions greater than one.

• MA.5.AR.1

  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.3.NSO.2

  Add and subtract multi-digit whole numbers. Build an understanding of multiplication and division operations.
