Defining Attributes of Rectangles and Parallelograms

Illustrative MathematicsVaries

At early stages of understanding of geometric shapes, students describe shapes, but do not yet characterize shapes by their properties. One example of a misconception students have at this stage is that a rectangle has two short sides and two long sides. The purpose of this task is for students to identify the defining attributes of rectangles and parallelograms. This task should be completed after students have many experiences sorting shapes by attributes.
