my dear you can draw a face :the letter O is the face ,the letters a & e are eyes,the letter i is the nose & the letter u is the mouth ..
tell ur puipils these are the english vowels and we use an with them .
the rest are cosonants and we use a with them .
if the word was plural we don't use any of them .
then make exsersices to ensure they understood the point
