Quadrilateral Challenge

Amanda Grant & Sherry Akin
4th Grade
Eagle Springs Elementary School
Houston County Schools


Working in pairs, students will create the following quadrilaterals: parallelogram, rhombus, square, rectangle, trapezoid. They will identify the attributes of each quadrilateral, then compare and contrast the attributes of different quadrilaterals.

Illustrative Task
Students will work in pairs. They will first construct an example of each quadrilateral (parallelogram, square, rectangle, trapezoid, and rhombus) on their quadrilateral mats. After they have created each quadrilateral, the students will determine the attributes of each figure by sorting the attribute cards. Once students feel they have sorted the attributes correctly and matched them to the correct quadrilateral, they will then glue the cards underneath the figures that they have created. Finally, students will use their journals. They will choose 2 quadrilaterals and compare and contrast their attributes.

GPS Addressed
M4G1 Students will define and identify the characteristics of geometric figures through examination and construction.
  1. Describe parallel and perpendicular lines in plane geometric figures.
  2. Examine and classify quadrilaterals (including parallelograms, squares, rectangles, trapezoids, and rhombi).
  3. Compare and contrast the relationships among quadrilaterals.

Video Information
Use these questions to guide your thinking about some of the important teacher ideas in the lesson featured in the video clip.
  1. What kinds of questions does the teacher ask to promote students’ problem solving?
  2. How is the teacher gauging students’ current understandings and building from those understandings?
  3. Consider the GPS standards listed with this video. How does the lesson featured in this video address each of these?
  4. What makes this lesson different from lessons you have taught on this topic?
