- by Teachwire
1 | Percentage puzzles
Percentages are commonplace in everyday life, but can be sometimes be confusing and difficult to interpret. In this lesson plan by Colin Foster, students get to grips with a series of puzzles aimed at showing what changes in percentage actually mean.
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.
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.
