Unit Description: Unit Description: : Unit 3 Triangles and More Triangles
· How can classifying triangles identify their special characteristics?
· What special relationships occur between congruent triangles and similar triangles?
· What special properties exist in a right triangle that makes it unique?
· How can special segments of a triangle be used to solve real-world problems?
· How can points of concurrency be used in real- world situations?

Assessments: We are doing an art project on tessellations that will be due 11/11/09. This project has been started in class, but will need to be finished at home. Students need to provide their own crayons, markers, or colored pencils to complete this project.
How will I address literacy this week? We will use vocabulary cards to learn the vocabulary of triangles.
