How to teach this

Make this a counting exercise, not a naming one. Have your student bracket every subject and verb pair first, then mark which brackets could stand alone. The label falls out of the two numbers, and students who count stop guessing from commas. The trap that catches almost everyone is the compound verb: we sanded the rail and painted the porch has one subject and one bracket, so it is simple. Practice a few of those on purpose before moving to the four-way sort.

Watch for: Two verbs do not make a compound sentence. We packed the cart and wiped the tables has one subject and stays simple. Length is not the test. A simple sentence can run fifteen words if it never adds a second subject and verb pair. A semicolon joins a compound sentence just as a comma and a conjunction do. The mark is different; the count is the same.
