… another picky thing

So “Time to know” has a new thing out — but hey, I get to leave in a hurry.   The ratio lesson says that 5 people will collect bottles in the city for every 3 people collecting bottles on the beach.

So, 700 bottles were collected in the city…we need to figure out the bottles collected from the beach.

So… people are the same as bottles?

Fact is, that later in their math lives, students really are sometimes expected to do more than “figure out what the procedure is and stick the numbers in the problem where they look right — the words will only confuse you.”  If we were instructing well, they would be learning to ask questions about exactly that kind of assumption.
