Reflection: Quizzes Introducing Geometry Quiz: Four Triangles - Section 2: Quiz


A change I made this year was to make this quiz a group quiz instead of an individual quiz.  This was one of the best decisions I have made for the following reasons: (1) it communicated to students the value of having and working with thinking partners, (2) it encouraged students to have thoughtful conversations around the Four Triangles vocabulary terms (line symmetry, rotational symmetry, convex/concave, congruent) which are essential to students having a transformational lens in geometry—this was WAY better than some students getting it, others not getting it all, and us as a class just moving forward, and (3) it helped students to see that they were able to make a product that was higher quality because of the collective resources and talents of the group that are greater than each of them as individuals.

Introducing Geometry Quiz: Four Triangles

Unit 1: Creating Classroom Culture to Develop the Math Practices
Lesson 6 of 6

Objective: Students will be able to demonstrate their understanding of the Four-Triangles problem to determine line symmetry and rotational symmetry for a set of pentominoes.

Big Idea: On this short assessment, students will be able to apply lessons learned from the Four Triangles problem in a new context.
