Common Core Standards Partitioned Circles & Rectangles
Grade:	2nd Grade
Standard:	Math.2.G.2 or 2.G.A.2
Description:	Partition a rectangle into rows and columns of same-size squares and count to find the total number of them.
Standard:	Math.2.G.3 or 2.G.A.3
Description:	Partition circles and rectangles into two, three, or four equal shares, describe the shares using the words halves, thirds, half of, a third of, etc., and describe the whole as two halves, three thirds, four fourths. Recognize that equal shares of identical wholes need not have the same shape.

HALVES, THIRDS, AND FOURTHS

If a shape is partitioned into two equal shares, the shares can be described as halves.
One of the shares can be described as half of the whole shape.
The whole shape can be described as two halves.

If a shape is partitioned into three equal shares, the shares can be described as thirds.
One of the shares can be described as a third of the whole shape.
The whole shape can be described as three thirds.

If a shape is partitioned into four equal shares, the shares can be described as fourths.
One of the shares can be described as a fourth of the whole shape.
The whole shape can be described as four fourths.
