• Display the cover Chicka Chicka 1, 2, 3! by Bill Martin, Jr. and share the title, author, and illustrator information with the class.
• Read aloud the first part of the book (stop once the number reaches 20), pausing to take special notice of how the numbers are ordered.
• Have students turn and talk to share with a partner answers to the following questions, "Do you think the numbers went into the tree in a special order? Which number came first? How about last?" (review the images from the book showing the numbers in the tree).
• Say, "Today, we are going to practice putting our own numbers in order!"
