A mnemonic is something that helps us remember things.
For example, some people use the first letters of the saying 'Richard of York gained battle in vain' to help them remember the colours of the rainbow (red, orange, yellow, green, blue, indigo, violet).
Mnemonics can be very helpful when we are trying to spell difficult words.
'Big elephants can always understand small elephants' is a well-known mnemonic for spelling 'because', but there are many others, too.
In this worksheet you can practise using mnemonics to help with spellings, but you can also make up your own mnemonics. A good mnemonic can be anything that helps you remember what you need to remember!
