bath towels vs soap

Be required to carry 30 bath towels OR 80 bars of soap? The distance or duration is up to you, but come up with a standard for the class. Also, some Google searches may be necessary to make your decision.

Whichever option you choose, justify your reasoning with mathematics. Maybe you can stack bars of soap in an array that’s easy to carry. Maybe you can load up on bath towels.

How much does a bath towel weigh (on average)?

How much does a bar of soap weigh (on average)?

This would also be a fun experiment to do in class with bath towels and bars of soap.

Purchase

Shake Mix A for $23

OR

Shake Mix B for $110?

Whichever answer you choose, justify your reasoning with mathematics.

To extend this conversation, it would be fun to ask the students follow-up questions:

What other information would you like to know about Shake A and/or Shake B?

How would that information influence your decision?

There are plenty of examples of protein shake labels on the Internet.  I would be encouraged to make this a part of a lesson that analyzes nutrition labels, regardless of whether or not my students were drinking protein shakes.  There is a HUGE market for them and students certainly know someone who is enamored with shakes for one reason or another.
