In this lesson, I show how to read a particular bathroom scale that measures in pounds. Then I weigh myself plus some other people on it. I also show the principle for weighing something bulky (a big bag in this case), where you need to use subtraction.
Lastly we attempt to weigh Mathy my mascot... Plus he does a surprise in the end!
