Content Standards: 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. Standard 3.MD.4 Generate measurement data by measuring lengths using rulers marked with halves and fourths of an inch. Show the data by marking a line plot where the horizontal scale is marked off in appropriate units-whole numbers, halves, or quarters . 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 size 1/ 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.
