How to teach this

Speed and structure: have your child underline the joining word and the comma before labeling. No comma-plus-conjunction between two complete ideas, no compound. That mechanical check catches the long simple sentences that fool the eye.

Watch for: Kids see the word and anywhere and shout compound. The test is whether BOTH sides of the joining word could stand alone as sentences. Long does not mean compound. A simple sentence can carry many describing words and still have one who-did-what pair.
