Common Core State Standards

 Math Math 3 Grade 3 G Geometry A Reason with shapes and their attributes 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 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape. Download Common Core State Standards (PDF 1.2 MB)
