About Apostrophes

What this skill is

Apostrophes are punctuation marks (') used for two distinct grammatical purposes: showing ownership in possessive nouns (the girl's book, the dogs' bone) and replacing omitted letters in contractions (is not -> isn't, they are -> they're). Solvers learn apostrophe placement rules, singular vs plural possessive apostrophes, contraction mechanics, possessive apostrophes, letter omission rules, and its/it's discrimination across writing, editing, spelling, and grammar lessons.

When children learn it

Basic contractions (can't, don't) and singular possessive apostrophes ('s) are introduced in 2nd grade. In 3rd through 5th grade, students master plural possessive apostrophes (s'), irregular plural possessives (children's), and possessive vs contraction homophones (its/it's, your/you're, their/they're) across language arts units, essay revision, and spelling drills.

Common Mistakes

  • Adding apostrophes to simple plural nouns that do not show ownership (writing 'apple's for sale' instead of 'apples for sale').
  • Confusing 'it's' (it is) with possessive 'its' (belonging to it) on editing passages and vocabulary quizzes.
  • Placing the apostrophe in the wrong letter position in contractions (writing 'is'nt' instead of 'isn't' during spelling).
