Subject: Mathematics (8), or Technology Education (K - 5)
Title: Growing in a Triangle
Description: Middle school students explore the Pythagorean Theorem by measuring and calculating diagonal lengths using the Pythagorean Theorem.  Students view an animated proof of the Pythagorean Theorem. They access an Internet site to view and discuss three examples of the Pythagorean Theorem.  Students apply knowledge of the Pythagorean Theorem to create a scale drawing of a plan to build a triangular raised bed garden for an outdoor classroom. Each group will present their plan to the class.

Subject: Mathematics (8 - 12)
Title: Proofs into Practice: The Pythagorean Theorem in the Real World
Description: The introduction of this lesson has students verifying the famous Pythagorean Theorem with a hands-on proof. Students will then apply the Theorem in one of two ways: by solving for the side lengths of a right triangle and by determining whether three side lengths could possibly form a right triangle. Finally, students will choose one of two real-life applicataions to explore, using the Pythagorean Theorem.
