Mum tweets her child's homework from school with spelling

A spelling exercise for year six pupils with obvious spelling mistakes made by the teacher has gone viral-after an irritated mum shared it on Twitter.
The homework task, supposedly designed to help the primary school children with their SATS exams, gives a list of six words they are expected to learn to spell. But two words -sincerely spelled incorrectly as "sincerley" and immediately spelled as "immediateley"- stick out as obvious errors.
There was also a typo in the last sentence where the word 'you' should read 'your.'
