  • 8 of the Best Percentage Increase and Decrease Teaching Resources for KS3 Maths

2 | One-step increases and decreases

Mark-ups in the one-step method are more efficient than the two-step method but are more difficult to understand. One significant obstacle to understanding is a common view that percentages over 100 are impossible. Yet one-step mark-ups require such percentages.

This resource offers a handful of activities to help students address any misconceptions and includes a handy worksheet too. It’s from New Zealand, so the figures are in dollars, but the sums, of course, remain the same.

Check it out here.


3 | Using percentages to increase quantities

In this resource students make links between percentages, decimals and fractions, represent percentage increase and decrease as multiplication and recognise the inverse relationship between increases and decreases.

It confronts any gaps and misconceptions in prior learning and build new conceptual links between percentages, decimals and fractions.

It also includes printable cards for you to use with increases in percentages, words, money and decimals.
