Introduction: Begin the lesson by asking the students if they have ever heard of Pythagoras or the Pythagorean Theorem. Explain that Pythagoras was a Greek mathematician who discovered a very important rule that helps us find the length of the sides of a right-angled triangle. Tell the students that they will be learning about this rule today.

Lesson Outline: 1. Define what a right-angled triangle is and identify the hypotenuse, adjacent and opposite sides. 2. Introduce the Pythagorean Theorem and explain how it works. 3. Demonstrate how to use the theorem to find the length of the hypotenuse or one of the other sides. 4. Provide examples for the students to practice using the theorem. 5. Challenge the students to apply the theorem to real-life situations.

Questioning: Throughout the lesson, ask the students questions to check their understanding. For example: - What is a right-angled triangle? - What is the hypotenuse? - How does the Pythagorean Theorem work? - Can you give an example of how to use the theorem?

Assessment: To assess the students’ understanding of the Pythagorean Theorem, provide them with a worksheet that includes a variety of questions that require them to use the theorem to find the length of the hypotenuse or one of the other sides. You can also ask them to explain how they arrived at their answers.

Differentiation: To differentiate the lesson for students with different learning needs, provide additional support for those who need it and challenge those who are ready for more advanced work. For example, you can provide visual aids or manipulatives for students who need extra help understanding the concept, and provide more challenging problems for students who are ready for a greater challenge.

Plenary: To wrap up the lesson, ask the students to share what they have learned about the Pythagorean Theorem. You can also provide a summary of the key points of the lesson and ask the students to reflect on how they can apply this knowledge in their everyday lives.
