How do we use integers in everyday life?

Hi Stephanie,

When you get home, look at today's mail. How many integers do you see 
on the envelopes? What are they being used for? 

Do you have any paper money in your pocket? How many integers do you 
see on the bills? What are they being used for? 

On your way home, look at the cars that you pass. How many integers do 
you see on the license plates? What are they being used for? 

On your first day of school, how did you find your locker? Was an 
integer involved? What role did it play? 

The next time you want to make a recipe, see how many integers appear 
in it. (Don't forget instructions like 'Makes six 4-ounce servings' 
and 'Bake at 375 degrees for 40 minutes'.) What are they being used 
for? 

Why is there a '29' in your email address? What would you do if you 
wanted to call your friend on the telephone? How do you know when 
Spring Break is going to start? How can you tell whether you're going 
to be late for school? 

Does this help?
