From SINE (Success In Numeracy Education) conference run by the CEO
This activity is sooo easy to prepare. Best to have an example or IWB file to guide students on what to do (see screen shot below) to get them started so you can focus on individuals that need more help
I got students to highlight or colour the common percentages (10%, 20%, 25%, 50%, 75%, 100% ) which they should of memorised. I also get them to simplify fractions if possible and write it in brackets next to it.
