Help students quickly grasp the difference between combinations and permutations with this concise set of notes and practice problems.

Each handout explains the core formula and guides students to identify if order matters in each problem. If it doesn’t, students skip the problem on that sheet and solve it on the other, making the two worksheets complementary.

This resource is designed as a fast, focused review—perfect for IB Math, AP Stats, or any course covering counting techniques without overwhelming theory.

What’s Included:

• Clear notes on combinations and permutations
  
• Practice problems to identify when order matters
  
• Complementary worksheets for skip-and-switch solving
  
• Printable PDFs with answer keys (if needed)
  

Perfect for:

✔️ Quick reviews or test prep
✔️ IB Math AI and AP Statistics
✔️ Introduction to counting techniques
✔️ Homework or classroom practice
