Hattie's Whose-Is-It — Possessive Nouns (Grade 1)

About this activity

Hattie the hedgehog runs the lost-and-found, where everything belongs to one owner — the dog's bone, the cat's ball, the bird's nest, the king's crown — and each round names an owner and the thing they own so the child can tap the word that shows ONE owner owns it. It's an interactive Grade 1 grammar activity that runs in the browser, with no account.

The big idea is the singular possessive: when one owner owns something, we add an apostrophe and an s. The child has to spot the form with the apostrophe in the right place rather than a plain plural that just adds s, so the choice turns on punctuation and meaning, not just spelling. Tying each one to a found object keeps the abstract apostrophe rule grounded in who the thing belongs to.

It is aligned to Common Core L.1.1.b — using singular possessive nouns, formed with an apostrophe and s. No timer, no score — just calm, playful practice.
