AL.NF. Number and Operations – Fractions
Build fractions from unit fractions by applying and extending previous understandings of operations on whole numbers.
NF.15. Apply and extend previous understandings of multiplication to multiply a fraction by a whole number. [4-NF4]
NF.15.a. Understand a fraction a/b as a multiple of 1/b. [4-NF4a]
Understand decimal notation for fractions, and compare decimal fractions.
NF.16. 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 and 100. (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-NF5]
NF.17. Use decimal notation for fractions with denominators 10 or 100. [4-NF6]
