Making a Pattern

Lucas loves his first-grade classroom! He found patterns around the room. Can you help him finish each pattern?

A pattern has items that repeat. A pattern can look like this. This is called an AB pattern. A pattern can also look like this. This is called an AAB pattern. We will finish the patterns Lucas finds by adding one more item to them.
