We need to learn how to spell. It's essential if we're to communicate using written text.
To find out if someone can spell a word a spelling test can be used. However, this does not need to be always done through the means of 'adult reads word, child writes word and then a score out of ten is produced'.
Yes, still use the 'traditional' spelling test sometimes, but how's about trying some of these too:
Anagrams: Provide the children anagrams of the words for them to then unscramble.
Crosswords: Give the children clues to a word's meaning or sentences with gaps.
Sentences: Write out some sentences. Some using the word correctly, others where the word's used incorrectly. Good for homophones and apostrophes.
Text: Provide a text with the words spelled incorrectly within in. Children correct the words.
Wordsearches: Put the words into a wordsearch for the children to find.
These often provide support, interest and engagement in the learning of spelling rules, patterns or key words for a particular topic. Using these also provides the opportunity to assess the children's understanding of a word's meaning.
