How much does it cost to mail a package in Canada? What factors determine the cost of postage? If you have ever put a box in the mail at a Canada Post location, you'll notice the mail person do several things. First they put the box on a scale, then they measure the dimensions of the box with a measuring tape. Finally, they read the postal code for the destination and input it all into their computer. Then they'll tell you the price to mail it.
Getting students to measure items with a variety of measurement tools is great practice to get familiar with metric and imperial measurement systems as well as becoming familiar with common measurement units. Sometimes this practice is just measuring lines on a worksheet or measuring objects around the classroom (paperclips, pencils, desks, etc.). This can seem a bit trivial. I was hunting for measurement with a purpose and thought of the measurements that postal employees do. It turns out, you can find the rate for mailing a package by using a page on Canada Post's website.
The students seemed to enjoy the activity and got some purposeful practice using metric and imperial measurements.
