Expanding sentences across the grades

1st grade

Expanding sentences worksheets for first grade start with a tiny sentence like The dog barked, plus one growth word in parentheses. Your child writes the bigger sentence on the line. It is the first step from writing short sentences to writing interesting ones.

2nd grade

Second grade expanding worksheets add two growth pieces per sentence: a how word and a where or when phrase. Your child weaves both into the sentence and writes it out. A capitalized cue like (After lunch,) signals that the piece opens the sentence.

3rd grade

Third grade expanding sentences worksheets use richer pieces and longer results. Your child builds each sentence, keeping the pieces in an order that reads naturally, and the answer key shows the model sentence for a quick check.
