Talking about proportions in my Pre-Pre-Algebra class (called Integrated Math).   We got on the topic of exchange rates.  A student asked how you can make money through exchange rates.   I’m a big fan of these Google graphs.  Lots of questions to ask.   We assumed we invested $1000 in Euros and exchanged them again to see if we made profits.  Lots of questions you can explore here…. also a very scalable problem for higher classes.
