Geo Board Lesson Plan(2)

I found this lesson on the cd. It is called Pythagoras Delivers the Mail. The objectice of this lesson is to devise methods for finding areas, learn about Pythogorean Theorem. The lesson starts with the students creating a triangle, any size, using the geoboard and drawing it on the center of a dot paper. Using a ruler draw a square congruent to the side of the triangle. Then they would need to find the area of each of the squares. Repeat the process with an obtuse triangle and an acute triangle. Students will then share their results with each other. Students will be told that there is a relationship to the squares and the right triangles. Students should notice a relatioship known as Pythogogearn Theorem. Students will be presented with a real life problem to relate their understanding to the lesson.
