How we explain it

Children can open this short lesson before they practice.

  1. “and” adds an idea; “but” shows something different; “so” shows a result; “or” gives a choice.
  2. Put a comma before the joining word in a compound sentence.
  3. Read both ideas and ask how they connect.

Example: Which word best joins the ideas? It was raining, ___ we stayed inside. Staying inside happened because of the rain. A result uses “so”. Answer: so
