I never said it was a good question and the issue so many of you have is what's causing the uproar and is a systemic problem with the direction education is heading as a whole.
As it was originally written with each piece of information on a separate line
There were some people on a train.
19 people get off the train at the first stop.
17 people get on the train. Now there are 63 people on the train.
How many people were on the train to begin with?
The expectation is that students are to immediately eliminate the second line since we are not concerned with what happens at the first stop since it does not affect how many people were originally on the train.
You can disagree all you want, it is what it is and it is what educators in the US and overseas are dealing with every day. For instance, some of my geometry kids recently took the PARCC exam, likely the hardest math test they will have taken up to this point in their lives and it is a cumulative exam encompassing algebra skills and the entire geometry curriculum, with ~3 months left in the school year. Somehow that's fair.
These problems pop up and most teachers are saying to themselves, "Yea and......." Because this are the types of problems we deal with day to day as we prepare kids to take tests that many of them aren't ready for, for a wide variety of reasons. Including the fact that half or over half of the math tests are now ELA tests as well in order to decipher the problem.
