Standards:

Equivalent Fractions and Comparison:

MAFS.4.NF.1.1 Explain why a fraction a/b is equivalent to a fraction (nxa)/(nxb) by using visualfraction models, with attention to how the number and size of the parts differ even though the two fractions themselves are the same size. Use this principle to recognize and generate equivalent fractions.

MAFS.4.NF.1.2 Compare two fractions with1different numerators and different denominators, e.g., by creating common denominators or numerators, or by comparing to a benchmark fraction such as . Recognize that comparisons are

valid only when the two fractions refer to the same whole. Record the results of comparisons with symbols >, =, or <, and justify the conclusions, e.g., by using a visual fraction model.

MAFS.4.NF.2.3 Understand a fraction a/b with a> 1 as a sum of fractions 1/b

MAFS.4.NF.2.3a Understand addition and subtraction of fractions as joining and separatingparts referring to the same whole.

MAFS.4.NF.2.3b Decompose a fraction into a sum of fractions with the same denominator in more than one way, recording each decomposition by an equation. Justify decompositions, e.g., by using a visual fraction model.

MAFS.4.NF.2.3c 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.

MAFS.4.NF.2.3d Solve word problems involving addition and subtraction of fractions referring to the same whole and having like denominators, e.g., by using visual fraction models and equations to represent the problem.

Multiplying Fractions:

MAFS.4.NF.2 Build fractions from unit fractions by applying and extending previous understanding of operations on whole numbers.

MAFS.4.NF.2.4 Apply and extend previous understandings of multiplication to multiply a fraction by a whole number.

MAFS.4.NF.2.4a Understand a fraction a/b as a multiple of 1/b.

MAFS.4.NF.2.4b Understand a multiple of a/b as a multiple of a/b, and use this understanding to multiply a fraction by a whole number.

MAFS.4.NF.2.4c Solve word problems involving multiplication of a fraction by a whole number, e.g., by using visual fraction models and equations to represent theproblem. For example, if each person at a party will eat 8 of a pound of roast beef, and there will be 5 people at the party, how many pounds of roast beef will be needed? Between what two whole numbers does your answer lie?

Relating Fractions and Decimals:

MAFS.4.NF.3Understand decimal notation for fractions, and compare decimal fractions.

MAFS.4.NF.3.5Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 and 100.

MAFS.4.NF.3 Understand decimal notation for fractions, and compare decimal fractions.

MAFS.4.NF.3.6 Use decimal notation for fractions with denominators 10 or 100.

MAFS.4.NF.3.7 Compare two decimals to hundredths by reasoning about their size. Recognize that comparisons are valid only when the two decimals refer to the same whole. Record the results of comparisons with the symbols >, =, or <, and justify the conclusions, e.g., by using a visual model.
