How to teach this

Frame each conjunction as a job: and is the adder, but is the difference-spotter, or is the chooser. Read the sentence twice with different joiners and ask which one tells the truth about the two ideas. That "tells the truth" framing works better with 7-year-olds than talking about clauses.

Watch for: The conjunctions aren't interchangeable: 'I fell and I laughed' tells a different story than 'I fell, but I laughed'. Because is a joining word too, but it isn't a coordinating conjunction. The core set here is and, but, or, so, yet.
