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.

Would You Rather…

Pounds of coins

RECEIVE 500 POUNDS OF PENNIES

OR

40 POUNDS OF QUARTERS? (h/t @approx_normal for this one)

Whichever option students choose, be sure to justify the reasoning with mathematics.

Data from the US Mint might help.

After students finish, have them contemplate what they’re going to do with all that coin!

This is based on a true story. It might also be fun to do some fact-checking and hypothesize why the numbers are different
