This activity helps students develop an understanding of graphical representations, interpret and analyze line plots, and determine the best way to display data.

This activity is designed to help students overcome the confusion that can arise when they learn that a square is also a rectangle—and a rhombus and a parallelogram. Students create a flowchart to visualize the properties of quadrilaterals. In the finished flowchart, the quadrilateral is at the top and the square is at the bottom, because the square has the greatest number of properties.

This activity gives students the opportunity to use concrete and dynamic representations of the shapes. At the completion of this activity, students will have a discovered a list of properties for each of the six special quadrilaterals. The final page of the quiz enables students to summarize all their findings in a table that can be retained for future use.
