Arizona's College and Career Ready Standards
AZ.4.NF. Number and Operations – Fractions (NF)
4.NF.B. Build fractions from unit fractions by applying and extending previous understanding of operations on whole numbers.
4.NF.B.4. Build fractions from unit fractions.
4.NF.B.4.a. Understand a fraction a/b as a multiple of a unit fraction 1/b. In general, a/b = a x 1/b.
4.NF.C. Understand decimal notation for fractions, and compare decimal fractions.
4.NF.C.5. Express a fraction with denominator 10 as an equivalent fraction with denominator 100, and use this technique to add two fractions with respective denominators 10 (tenths) and 100 (hundredths). For example, express 3/10 as 30/100, and ad 3/10 + 4/100 = 34/100. (Note: Students who can generate equivalent fractions can develop strategies for adding fractions with unlike denominators in general. But addition and subtraction with unlike denominators, in general, is not a requirement at this grade.)
4.NF.C.6. Use decimal notation for fractions with denominators 10 (tenths) or 100 (hundredths), and locate these decimals on a number line.
