This is a four page worksheet/handout to teach/practice/master the grammatical double negative mistakes. This worksheet includes:
Information on what double negatives are, and what the negative words are
Identifying negative words in sentences, and correcting them to positive words
Completing sentences to avoid double negatives
Identifying correctly written sentences
It really helps the students if they can see what the negative words are, and have practice with seeing double negative sentences. Then, they can become more familiar with how sentences should and shouldn't be written.
