Pupils will get to take a mini mint whenever they have correctly used:
M for the months of the year (and days!)
I for the pronoun 'I'
N for names (people, places, countries, brands, important groups)
T for titles such as Mr, Mrs, Dr, Sir, madam
S for the start of sentences.
Thanks to Raewyn Green from the Southland Campus of the University of Otago for the acronym hint!
