Vocabulary Strategy: Context Clues: Synonyms Synonyms are different words that mean almost the same thing. Sometimes an author writes a synonym near a difficult word to help readers understand the word. 1.Read the words and sentences around the unknown word. Is there a synonym? 2.To help find synonyms, look for or like, or look for a word set off by commas. 3.Try using the synonym in place of the unknown word. Does this meaning make sense? 4.If these tips do not help, look up the unknown word in the dictionary or talk with a friend about it. As you read “Small but Mighty,” check the context of words you don’t know. See if a nearby synonym gives a clue to a word’s meaning.

The descriptions of honey ant nests and repletes on p. 444, paragraphs 1-3, contain many facts that need to be read carefully to understand. This lets you know the author is writing to inform. Identify text features that indicate that the author is writing to inform.
Metaphor A metaphor is a comparison between two unlike things that are alike in at least one way. In a metaphor, the similarity is implied – not stated using words of comparison.
