This is aligned with the following California State Standards:
Communicate understanding of a unit by recognizing a group of countable objects. Communicate understanding of wholeness by recognizing an object that has all the parts joined together. Recognize parts of an object and the whole object.
Recognize two glasses with an equal amount of liquid. Divide familiar shapes, such as circles, squares, and/or rectangles, into two or more equal parts.
Recognize a fraction as a number expressed as a quotient of two integers in the form a/b, with b not equal to zero. Demonstrate understanding of a unit fraction (e.g., 1/4) as the quantity formed by one part when a whole is partitioned into n (e.g., 4) equal parts. Recognize the number above the fraction bar as the numerator and the number below the fraction bar as the denominator.
Communicate understanding that when a whole is divided into more parts, each part is smaller than when that same whole is divided into fewer parts (e.g., 1/5 is smaller than 1/2 because in 1/5 the whole is divided into five equal parts and in 1/2 the same whole is divided into two equal parts).
Communicate understanding that the numerator represents a number of equal parts and the denominator represents how many equal parts make up the whole. Compare fractions (i.e., which fraction is greater than and which is less than) using manipulatives. Add fractions with common denominators (e.g., 2/5 + 1/5 = 3/5), and decompose fractions into sums of unit fractions with the same denominator (e.g., 3/7 = 1/7 + 1/7 + 1/7).
