When Miss Weinstein packs shoes for a trip, they often have a purpose. For example, the purpose of her high heels is to look fancy at a party she may be attending. The purpose of her snow boots is to stay warm when she goes skiing. She wouldn't dare wear her soccer shoes at the fancy party or her snow boots at the beach. "Purpose" is similar to a job or "the reason why."
Just like shoes, books have a purpose. Today we learned that we read different books for different reasons. We will continue to explore the shoe analogy next week as we prepare to choose our own books for our book boxes.
