13. Use Appropriate Tools What time does Mia have to leave for school if it takes 45 minutes to get to school? School starts at 7:30 A.M. Draw a number line to explain.

To figure out when Mia needs to leave for school, we can count backward from 7:30 A.M. If it takes her 45 minutes to get to school, we start at 7:30 and move back 45 minutes. If we visualize this on a number line, we start at 7:30 A.M. and find 7:15 A.M. (which is 15 minutes back) and then go back another 30 minutes to land on 6:45 A.M. So, Mia should leave at 6:45 A.M. to ensure she arrives on time! Let’s make school mornings a little easier by planning ahead! Set an alarm for 6:30 A.M. to give Mia some extra time for breakfast or finding her shoes. And hey, a couple of minutes early can turn chaotic morning routines into a leisurely stroll to school!
