Discounted Watches

Some more fun everyday math skills-

We got Josh (8y) a new watch the other day. He's checking out all the watches on the display and notices the one he likes is 20% off.

Josh- Hmmmm, so how much does that make it?

Me- Well how much is it without the discount?

Josh- $20

Me- I'd start with finding 10% of 20 and go from there.

Josh- Yeah, so 10% of 20 is 2, and another 10% would be 2, so 20% would be 4. So it would be $16.

Yet another example of how unschoolers can learn math.
