GCSE Maths :|: Scale Factor Method 3 :|: Percentages Series/Parallel Reversing a Percentage Increase

In this LESSON PRIMER, we are learning how to overcome the most difficult type of questions on percentages that arise at GCSE level. We show how the Scale Factor Method can force students to evaluate the question more rigorously and effortlessly deals with these tricky questions on Pie Charts, Percentages in Parallel, Percentages in Series, Revesing a Percentage Increase/Decrease and Simple Interest Calculations.
"LESSON PRIMERS" are designed to engage our pupils with the material before the lesson begins; setting the stage for deeper learning and discussion in the classroom. So, these videos aren't really intended to be used without the rest of our multi-faceted learning program, but if that's what you are doing, then we hope this helped you...
