Students will be placed in groups and taken on a Geometry walk around school. Using a digital camera, groups will locate polygons and quadrilaterals. Groups will take a picture with their polygon or quadrilateral. Upon returning to class, pictures will be printed and given to each group. Group members will list the identifying characteristics of their polygon or quadrilateral. Groups will present their picture to the class. Groups will compare and contrast their polygons with polygons being presented.

The lesson will require students to identify the characteristics of polygons and quadrilaterals. Students understand polygons better when they can relate them to something in their own lives. After a PowerPoint presentation of the identifying characteristics of polygons and the special names of quadrilaterals, students will be lead on a “geometry walk” to create pictures of polygons they find in their surroundings. As groups work together to identify the characteristics of their chosen polygon or quadrilateral, they will need to communicate with precision of language and thought. Group members will need to communicate their understanding by verbalizing the identifying characteristics of their chosen polygon. For example, if they chose a stop sign, they will need to understand that the sign has eight sides and that an eight sided polygon is called an octagon. As each group member shares their understanding of the characteristics to identify their chosen polygon, other group members will check for accuracy by discussing their understanding of the identifying characteristics. All members of the group must agree with the identified characteristics before pictures will be taken. Upon returning to class and printing the pictures, groups will list all characteristics that identify their polygon and prepare a presentation for the class. As students prepare their presentations, they will need to be persistent in completing the task. They will need to approach the task systematically as they work together to determine the finishing touches to their presentation. If group members determine that their identifying characteristics do not fit as they listen to other groups’ presentations, they need to try again to determine identifying factors.
