#### Introduction

(5 minutes)
• Tell students the story problem, "Josephine needs to read 20 minutes each night for homework. Yesterday, she sat down to do her homework, but she kept getting interrupted! She read for eight minutes, and then she had to stop to feed her cat. (Write "8 minutes" on the board.) She read for five more minutes, and then she had to open the door for her brother. (Write "5 minutes".) She read for five more minutes, and then she had to stop to help her dad cook dinner! (Write "5 minutes".) Did Josephine reach her goal? Did she finish her homework? How do you know?"
• Instruct students to turn and talk to a partner about ways to solve the problem.
• Invite students to share strategies for solving the problem. For example, counting on using the number line or drawing a picture.
• Think aloud, "We need to add to find the total number of minutes. We know that 5 + 5 = 10, and that 10 is a friendly number. Next we can add 10 + 8 = 18. Remember that we can add the numbers in any order. Give me a thumbs up if you think Josephine finished her homework.
• Comment that Josephine needs to read for two more minutes to reach her goal of reading for 20 minutes.
