Say Why It Happened
Students take supported cause pairs from a short case microtext and move through controlled → guided → free practice with a controlled connector set, checking each sentence against a clause-structure and punctuation card.
Grammar target
Write a cause–effect sentence for a supported cause pair using because, since, so, therefore, as a result, or due to — with correct clause structure and punctuation.
Essential question
How do I say why something happened without over-claiming what the evidence shows?
Objective
Students can produce grammatically accurate cause–effect sentences using because, since, so, therefore, as a result, and due to, matching the correct clause structure and punctuation to each connector.
