The spelling pattern
Every word on this list contains -sion (vision). Seeing the same letters in many words helps children spot the pattern and spell new words that follow it. Level 2 adds longer and less frequent words.
Ways to practise
Read the list aloud, then cover each word and write it from memory.
Use the fill-in sheet below: the pattern letters are blanked out.
Sort the words by length or by where the pattern appears (start, middle or end).
Where the pattern appears
At the end (20): delusion, illusion, invasion, omission, revision, admission, dimension, exclusion, explosion, inclusion, obsession, precision, provision, recursion, compassion, compulsion, conversion, depression, oppression, persuasion.
Sorting the words like this is a good first activity: children say each word, find the -sion (vision) letters and decide which group it belongs to. It shows that the same letters keep the same sound wherever they appear in a word.
Running a spelling test with this list
Read each word aloud, use it in a short sentence, then read it once more. Children write the word without looking. Mark the test with the list above and practise any misspelled words again the next day. Five or ten words at a time is plenty for younger children.
