Wondering if we can make this a math club problem? Provide a spreadsheet of capital-to-capital distances and ask students to design a "best" path. This is a very famous and very difficult problem. It would connect into the scaling problem we had with the planets in the fall & the US map optimization. Also plays well into the underlying "strategy" conversations we've been having.

devlin mathematics vs arithmetic computers

Knowing how to solve an equation is no longer a valuable human ability; what matters now is formulating the equation to solve that problem in the first place, and then taking the result of the machine solution to the equation and making use of it.

Today, we have instant access to vast amounts of information and to unlimited computing power. Both are now utilities, much like water and electricity. And that has led to a revolution in the mathematics ordinary citizens need in order to lead a fulfilling, productive life. In a world where procedural (i.e., algorithmic) mathematics is available at the push of a button, the need has shifted to what I and others have been calling mathematical thinking.

Unfortunately, many Americans were never taught to understand arithmetic, they were just trained to execute procedures. It's not their kids who are being short-changed. They—the parents—were!

Another great Devlin posting on why we need to be doing MUCH MORE thinking and pattern recognition (mathematics) and FAR LESS procedural computations (arithmetic).

Very funny (& true) first comment. I wonder about making this a much more open ended problem. What if you were told that Samantha inserted $20 and got $2.60 in change? What if she inserted $20 and got 12 tokens? What if she got 12 tokens and $2.60 in change, but you weren't told what she inserted? What would these discussions look like?

This is a great article! And I had to chuckle at the reference to shark week since my husband has been watching it. What a great project idea....how can we solve this problem?
