Topic 12:

• fraction • unit fraction • numerator • denominator • nearest fourth inch • line plot • nearest half inch

Standard 3.G.2 Partition shapes into parts with equal areas. Express the area of each part as a unit fraction of the whole. For example, partition a shape into four parts with equal area, and describe the area of each part as ¼ of the area of the shape.

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 parts of size 1/ b . For example: 1/4 + 1/4 + 1/4 =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

defining 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.
