In Grade 3, instructional time should focus on four critical areas: (1) developing understanding of multiplication and division and strategies for multiplication and division within 100; (2) developing understanding of fractions, especially unit fractions (fractions with numerator 1); (3) developing understanding of the structure of rectangular arrays and of area; and (4) describing and analyzing two-dimensional shapes.
Understand that shapes in different categories (e.g., rhombuses, rectangles, and others) may share attributes (e.g., having four sides), and that the shared attributes can define a larger category (e.g., quadrilaterals). Recognize rhombuses, rectangles, and squares as examples of quadrilaterals, and draw examples of quadrilaterals that do not belong to any of these subcategories.

Shape Categories
|
2 - Understand (different shape categories may share attributes)
2 - Understand (shared attributes can define a larger category)
1 - Recognize (rhombuses, rectangles, and squares are quadrilaterals)
4 - Draw (nonrhombuse, nonrectangle, and nonsquare quadrilaterals)
|
2 - I can understand that different shape categories may share the same attributes.
2 - I can understand that shared attributes can define a larger shape category.
1 - I can recognize rhombuses, rectangles, and squares are quadrilaterals.
4 - I can draw quadrilaterals that are not rhombuses, rectangles, or squares.

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.
