This leson can be taught in groups or individually. The major limitation to the lesson is the amount of computers and tangrams are avilable for class.
Students will use the tangrams to build or choose the appropriate triangle being discussed. The ywill use the definitions to find the triangle in question. In groups, the students will construct triangles on Geometer's Sketchpad and other students will classify the triangles an identify the parts of the constructed triangles.
Students will review the main ideas discussed in the lesson.
In your environment, find twenty triangles, draw the triangles as you seethem and classify the triangles according to their attributes (SIDE AND ANGLE).
