Teach the Pythagorean Theorem with clarity and structure using this complete lesson and worksheet bundle. This resource combines a step-by-step PowerPoint lesson with a highly scaffolded worksheet, giving you everything needed to introduce, model, and reinforce how to find the hypotenuse in right-angled triangles.

Designed for effective instruction and minimal prep, this bundle follows a clear progression from teacher modelling to independent student practice.

What’s Included

PowerPoint Lesson

• Introduction to right angles and the hypotenuse
• Clear explanation of a² + b² = c²
• Fully worked examples
• Guided practice (We Do)
• Independent practice (You Do)
• Question sets with answers

Scaffolded Worksheet and Answer Key

• Identifying the hypotenuse
• Structured formula breakdown
• Guided example with working steps
• Differentiated practice:
  • Level 1: Highly scaffolded
  • Level 2: Partially scaffolded
  • Level 3: Independent

• Real-world applications (ladders, fields, distances)
• Extension question for deeper thinking

Learning Outcomes

Students will be able to:

• Identify the hypotenuse in right-angled triangles
• Apply the Pythagorean Theorem to calculate missing sides
• Substitute values correctly into a² + b² = c²
• Solve both abstract and real-world problems with clear working
