GCSE Maths 'Using the Product Rule for Counting' Differentiated Presentation

GCSE Higher Tier says ‘apply systematic listing strategies, including use of the product rule for counting (i.e. if there are m ways of doing one task and for each of these, there are n ways of doing another task, then the total number of ways the two tasks can be done is m × n ways)’.
A clear, colourful and carefully explained PowerPoint presentation building up the skills from simple matching problems to calculating combinations and permutations in a variety of realistic and original settings, with lots of opportunity for the learner to reflect, apply, and evaluate the problems.
Also available in my shop are two differentiated worksheets of adapted exam questions from sample and real GCSE assessments.
Plus a PDF version that will work on all operating systems.
