4th Grade

Alabama Course of Study Standards: 15

Model and justify decompositions of fractions and explain addition and subtraction of fractions as joining or separating parts referring to the same whole.

Arizona Academic Standards: 4.NF.B.3a

Common Core State Standards: Math.4.NF.3a or 4.NF.B.3.A

Kentucky Academic Standards (KAS): 4.NF.3.a

Mississippi College- and Career-Readiness Standards: 4.NF.3a

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

Georgia Standards of Excellence (GSE): 4.NR.4.4

Represent whole numbers and fractions as the sum of unit fractions.

Louisiana Academic Standards: 4.NF.B.3.a

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole. Example: 3/4 = 1/4 + 1/4 + 1/4.

Massachusetts Curriculum Frameworks: 4.NF.B.3.a

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole. (The whole can be a set of objects.)

North Carolina - Standard Course of Study: 4.NF.3.a

Understand addition and subtraction of fractions as joining and separating parts referring to the same whole.

Tennessee Academic Standards: 4.NF.B.3.a

Decompose a fraction into a sum of fractions with the same denominator in more than one way (e.g., 3/8 = 1/8 + 1/8 + 1/8; 3/8 = 1/8 + 2/8; 21/8 = 1 + 1 + 1/8 = 8/8 + 8/8 + 1/8), recording each decomposition by an equation. Justify decompositions by using a visual fraction model.

Alabama Course of Study Standards: 15.b

Add and subtract fractions and mixed numbers with like denominators using fraction equivalence, properties of operations, and the relationship between addition and subtraction.

Arizona Academic Standards: 4.NF.B.3c

Add and subtract mixed numbers with like denominators (e.g., by using properties of operations and the relationship between addition and subtraction and/or by replacing each mixed number with an equivalent fraction).

Common Core State Standards: Math.4.NF.3c or 4.NF.B.3.C

Kentucky Academic Standards (KAS): 4.NF.3.c

Mississippi College- and Career-Readiness Standards: 4.NF.3c

Add and subtract mixed numbers with like denominators, e.g., by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.

Georgia Standards of Excellence (GSE): 4.NR.4.6

Add and subtract fractions and mixed numbers with like denominators using a variety of tools.

North Carolina - Standard Course of Study: 4.NF.3.c

Add and subtract fractions, including mixed numbers with like denominators, by replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction.

New York State Next Generation Learning Standards: 4.NF.3.c

Add and subtract mixed numbers with like denominators.
e.g., replacing each mixed number with an equivalent fraction, and/or by using properties of operations and the relationship between addition and subtraction

Tennessee Academic Standards: 4.NF.B.3.c

Add and subtract mixed numbers with like denominators by replacing each mixed number with an equivalent fraction and/or by using properties of operations and the relationship between addition and subtraction.

Wisconsin Academic Standards: 4.NF.B.3.c

Add and subtract fractions, including mixed numbers, with like denominators (e.g., 3/8 + 2/8) and related denominators (e.g., 1/2 +1/4, 1/3 + 1/6) by using visual fraction models (e.g., tape diagrams and number lines), properties of operations, and the relationship between addition and subtraction.
