Just like a substitute teaches your class, /when she's asked to fill in for your teacher, /a pronoun steps in as a sub for a noun, / becoming the star of the feature. In this 20th anniversary edition of I and You and Don't Forget Who, author Brian Cleary and illustrator Brian Gable provide numerous examples of pronouns. The text's playful rhymes combine with fun illustrations to build understanding of how this part of speech is used. New Try It! features, updated back matter, and a fresh font make these editions extra special.
