Teachers may preview and explain each lesson before students start the lesson.  Have students look up the words  and write a sentence using each word in the lesson.  This will help them get used to using the dictionary.  If students get wrong answers, have them go back, look up the words, and rewrite the sentences.  You can assume that they guessed at the meaning and did not look the word up if they cannot write a proper sentence using the word.

When necessary, look back to get the correct meaning of each word before writing the sentence, then write the sentence.
