I use this when introducing new vocabulary words to my students. It helps to get them to think about how well they know each word. They will rate each word on a scale of 1-3. I encourage them to study words they rated a 1 or 2. If students rate a word a 3 they should be able to define it and use it correctly in a sentence.
This is a Word document. Vocabulary words are to be typed in the left column of the table and you can add more or less to suite your needs!
