Some percentage problems require students to work backwards – for example, rather than finding the sale price of an item after a percentage decrease, they might be given the sale price and be asked to find the original price.
We can use the multiplier method for these calculations. To calculate a percentage reduction, we would multiply the original value by the percentage multiplier. To work backwards, we use the inverse operation, division, so we divide the sale price by the percentage multiplier.
A good non-calculator method is to get students to equate the sale price with the reduced percentage, and then use known amounts to find 100%. For example, if an item costs £40 after a 20% reduction, £40 represents 80% of the original amount. Dividing £40 by 8 gives 10%, and multiplying by 10 gets back to 100%.
Looking forward, students can then progress to additional number worksheets, such as a standard form conversions worksheet. For students working at this level, we also have worksheets on topics like Pythagoras Theorem, trigonometry, vectors, simultaneous equations and laws of indices such as this index laws worksheet
There will be students in your class who require individual attention to help them succeed in their maths GCSEs. In a class of 30, it’s not always easy to provide.
