Triangle+Scavenger+Hunt+&+Analysis

=Triangle Scavenger Hunt & Analysis=

Objective
Students will analyze triangles, similar triangles, and special triangles (isosceles, equilateral, and right) by studying triangles in their environment.

Standard
Georgia GPS MM1G3 Students will discover, prove, and apply properties of triangles, quadrilaterals, and other polygons. c: Understand and use congruence postulates and theorems for triangles (SSS, SAS, ASA, AAS, HL). MM1P1, Students will solve problems (using appropriate technology) b: Solve problems that arise in mathematics and in other contexts. c: Apply and adapt a variety of appropriate strategies to solve problems. MM1P3, Students will communicate mathematically. a. Organize and consolidate their mathematical thinking through communication. b. Communicate their mathematical thinking coherently and clearly to peers, teachers, and others.

Materials

 * Mobile camera phone with MMS capability
 * Computer with internet access
 * Account on flickr, a photo sharing web site
 * Handout: Activity directions and guidelines with my rubric on the reverse

Warm Up & Engagement
Classify photos of everyday triangles as isosceles, equilateral, or right. Use 6 to 10 images from http://www.flickr.com/photos/mgolding/tags/triangles/.

Lesson

 * 1) Find 10 triangle examples in your everyday life. The class will take a trip during 1 class period. Outside of class time will be required by most students. The photos will be judged on variety, creativity, and whether you found “special triangles” (similar, congruent, isosceles, equilateral, or right).
 * 2) Photograph a triangle then upload it to your flickr account.
 * 3) Back at school, download the photo and use The GIMP photo editing software to mark the triangle’s interesting features.
 * 4) Reload them to flickr, so you have a before and after of each triangle.
 * 5) Add the photos to the Axiomatics flickr group so we can see all your triangles.

Assessment
Students will be graded on a group rubric for today’s work. I’ll be looking for the following:
 * At least 1 photo each of right, equilateral, and isosceles triangles.
 * That the geometry is correct on all labels.
 * Comments were left on peers’ photos.
 * That the elementary triangle geometry content is complete
