Mystery Quadrilateral!

Activity Overview

This activity could be used as an assessment after a unit on special quadrilaterals. Students are given an unknown mystery quadrilateral that looks like a square. By dragging the vertices of the mystery quadrilateral, students conjecture the true name of the quadrilateral. Students support their conjecture by taking appropriate measurements to support their conjectures.

Before the Activity

The associated .tns file should be downloaded onto the student handhelds. If you choose to have students type their conjectures into the document, you should be prepared to have students download their completed documents to your computer. You may also choose to have your students write their conjectures and support on paper; you should still check their documents for their support.
