(10 minutes)
• Read aloud the book, as you read point out the order of the numbers and how they match the number of cars on each page.
• Have students turn and talk to share with a partner answers to the question, "What would happen if I started counting the cars and started at nine?" Allow students a few minutes to share and then say, "Right! I would get all mixed up because I want to start at the smallest number and count in order."
• Point to the number posted and model counting aloud from 0-20.
• Use the Vocabulary Cards and Glossary to introduce and review Order, Greatest, and Least.
• Model counting aloud in a mixed-up order and see if students notice what you are doing. If not, say, "Whoops! That doesn't sound right! Let me try again." Remind students that when we count, we always count in the same OrderFrom 0-20.
(5 minutes)
• Explain that today the class is going to practise making a race track and racing their cars from 0-20.
• Model how to use one of the strips of tape and placing the number cards in order on the tape from 0-20 (make at least two mistakes in the order of the numbers).
• Ask the class to help make sure you put the numbers in order.
• Point to the cards as you count them aloud, pausing to see if the students notice your mistake.
• Invite students give a thumbs up or down to indicate if each of the individual numbers are ordered correctly as you count them a second time.

• Demonstrate how two students will race their cars from 0-20, counting aloud as they race.
(10 minutes)
• Explain that now students will get to practise ordering their very own race track!
• Tell students that before taping down their number cards, they will ask their partner to make sure they are ordered from least to greatest. Once both students have a completed the race track, they will get to take turns racing cars and counting aloud on both tracks.
