#### Introduction

(5 minutes)
• Display the first problem of the Expanded Form: Which One Doesn't Belong? worksheet. Have the students consider the options that exist for 30 seconds.
• Tell them to turn and talk to their partner about which number is out of place or does not belong with the other numbers.
• Remind students they need to have a reason for their answer. For example, "I think the number four doesn't belong because there are two fours and not one," or "I think the number five thousand is out of place because there is no value of five thousand in the largest number. It should be fifty-thousand instead."
• Listen for how students say the numbers and all the vocabulary they use to help guide the lesson and determine the amount of time to spend on vocabulary instruction.
