Systematic Listings and the Product Rule for Counting — Interactive Lesson (Ages 14–16)

Still listing outcomes one by one instead of multiplying to find the total instantly? This 17-slide interactive lesson gives pupils focused, self-marking practice using systematic listing and the product rule for counting.

Mastering Counting Methods in GCSE Maths

Pupils practise listing outcomes systematically and applying the product rule for counting, building the fluency within the GCSE Maths curriculum’s probability and combinatorics strand. Moving from listing every outcome by hand to multiplying choices together is a genuine step up in efficiency, and this lesson gives pupils focused practice recognising when each approach is appropriate.
