Understand quadrilaterals and their attributes.
3.G.1 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.
Students will understand that shapes that are different (rhombuses, rectangles, squares, trapezoids, and parallellograms) have similarities (e.g., having four sides). They will learn that these similarities can be grouped in a larger category (quadrilaterals). They will be able to recognize all the quadrilaterals (rhombuses, rectangles, squares, trapeziods, and parralellograms), label them, sort them, and draw them. They will also be able to identify quadrilaterals that do not belong to any of these subgroups.

Divide shapes into equal areas.
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 4 parts with equal area, and describe the area of each part as 1/4 of the area of the shape.  
This is taking a shape and being able to split it apart equally to make the shape into fraction pieces. Also taking a shape and seeing what other shapes it can be broken apart into.

Using grid paper have your child divide a shape multiple times always making sure the parts are equal. Challenge your child to justify to you how they know they came up with all the possible ways to divide the shape into fourths or that they know the numbers they could use to divide the shape (thirds, sixths, ninths, twelves, etc. or halves, fourths, eighths, tenths, etc.)
