Product Description
Core standards for geometry require students to identify quadrilaterals as four-side polygons beginning in second grade. In third grade, students are expected to recognize rhombuses, rectangles, and squares as quadrilaterals and to recognize their shared attributes. (Parallelograms are not mentioned in the standards, though they are included in this unit.)

In fourth grade, students classify two-dimensional shapes based on absence or presence of parallel or perpendicular lines, and angles of a specified size. In fifth grade, geometry standards require students to understand that attributes of a category of two-dimensional figures also belong to all subcategories of that category and to classify two-dimensional figures in a hierarchy based on properties.

Quadrilaterals are often confusing because one shape may fit in more than one subcategory. For example, a square is a rectangle and also a rhombus. A square is a parallelogram and a quadrilateral.
Activities in this packet are designed to provide plenty of opportunities for students to practice recognizing and classifying quadrilaterals.
You will receive:
A hierarchy chart showing relationships between quadrilaterals
Display pictures and labels for bulletin board or pocket chart
Math center activity
Math journal page
Flip Flap booklet
11 pages of worksheet practice activities

NOTE: There is confusion because of two different definitions of a trapezoid. Common Core standards do not provide a definition, so each state/district is left to decide which definition to use. This packet has been modified to include materials that fit each definition, so you may choose to use the pages that match the definition you are using.
