Cindy Holloway visited the seventh grade classroom and explained the different ways students could mail packages. They learned about express mail, priority mail, and standard mail (parcel post). The students had just finished studying volume. They were told to bring packages with
volumes of 3000 cubic centimeters, 2000 cubic centimeters, 1000 and 50 cubic centimeters. They brought four packages to school and weighed them. They chose locations in the United States using their initials. (i.e. Sarah Gosch sent a package to Savannah, Georgia) They located
the zipcodes using the Internet. Using the charts that Mrs. Holloway gave them, they were able to figure out the zone. They chose which way they wanted to mail the package and figured out the cost. They wrote math problems about their information. Here are some examples:
Dr. Jonathan MacIntosh sent some very ripe golden delicious apples to his daughter, living in Ripon, Wisconsin. The package, weighing 8 pounds, was sent priority mail. The zip code in Ripon is 54971. What did it cost to mail the package?
The baker in Bakersville, Louisiana wants to send a box of bottomless
bottles of spring water to Miss Spring Summersville of Spring Lake, Illinois.
The zipcode is 61546. The baker would like the bottles of bottomless
spring water to arrive within three days. How should he send it and
what would it cost to mail?
Bryan from Bryantown, Maryland is sending a package of hoods made out
of woods to Durrwood from Burrwood. The weight is 22 kilograms.
The zipcode in Bryantown is 70091. What would it cost to send the hoods
made out of woods priority mail?
The U.S. Postal Service handles 41 percent of the world’s mail volume, 630 million pieces every day. Japan handles 6 percent. How many pieces of mail travel through the United States in one year?
