How do I explain common vs proper nouns to a 2nd grader?

Try "any" versus "the one." A common noun is any city, any girl, any dog. A proper noun is the one you mean: Chicago, Maya, Rex. If you could point at lots of them, it's common. If it's a name, it's proper and gets a capital.

Why is sorting better than circling for this skill?

Because the skill is telling two groups apart, not finding words in a sentence. A sort forces a decision on every word. Each print pulls a new word bank at random, so a second round is almost never the same list.

How to teach this

Sorting works better than defining here, which is why this worksheet is a two-column sort. Seed it with pairs your child knows personally: our school and its actual name, our street and its street name, dog and your pet's name. The pairing makes the general-versus-specific idea concrete in a way definitions never do.

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.
