Every version prints on US Letter or A4, with its answer key on the last page.

How to teach this

Make it personal: dog is any dog, but your dog has a name, and names get capitals. Sort aloud together and let the capital letter itself be the clue at first; the deeper is-it-one-special-thing test grows naturally out of the sorting.

Watch for: A word isn't proper just because it starts a sentence with a capital. The capital has to belong to the word itself. Days, months, and holidays are proper nouns. School subjects like math are not.

Common questions about common and proper nouns

What's the simplest way to explain proper nouns?: Names get capitals. Your child's own name is the anchor: Mia is a special someone, girl is anyone. From there, pet names, days, and places follow the same pattern. One special thing, one capital letter.
My child capitalizes random words. Is that a problem?: It's a phase nearly every new writer visits; capitals feel important, so they get sprinkled. Sorting practice like this tightens the rule: capitals are for names, not for emphasis. Gentle correction plus sorting beats a lecture.
