How to teach this
Anchor each word to a gesture: and stacks two fists together, but flips a palm over, or holds out two open hands to choose between. Read the sentence aloud with each option and let your child hear which one the sentence wants. Their ear knows before the rule does.
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.
Common questions about coordinating conjunctions
- Which joining words should a 1st grader know?
- And, but, and or cover nearly everything a first grader says and reads. And adds more, but introduces a surprise, or offers a choice. So and because join the party in later grades once these three are automatic.
- How can I practice this away from the worksheet?
- Sentence tennis at dinner: you start (I like peas...), your child finishes with a joiner (...but I love corn). Speech is where these words live; the worksheet just makes the choosing visible.
