Apr.14-May 30

Content Standards: Standard 3.NF.1 Understand that a unit fraction has a numerator of one and a non-zero denominator. a. Understand a fraction 1/ b as the quantity formed by one part, when a whole is partitioned into b equal parts.

b. Understand a fraction a/b as the quantity formed by a part of size1/ b . For example: 1/4 + 1/4 + ¼ = 3/4.

Standard 3.NF.2 Understand a fraction as a number on the number line; represent fractions on a number line diagram. a. Represent a fraction 1/ b on a number line diagram by defning the interval from 0 to 1 as the whole and partitioning it into b equal parts. Recognize that each part has size 1/ b and that the endpoint of the part based at 0 locates the number 1/ b on the number line. b. Represent a fraction a/b on a number line diagram by marking off a length1/ b from 0. Recognize that the resulting interval has size a/b and that its endpoint locates the number a/b on the number line.

Standard 3.NF.3 Explain equivalence of fractions in special cases, and
