the tally marks for adding aren't new to common core. They've been being taught for at least several years. I'm not sure where they started but probably have more to do with inclusion and some of it's offshoots.

Common Core is a hot topic right now. Much like Obamacare, many seem to have cheered it's inception but now hate it's progression.

As far as ACT and SAT, no matter what method of problem solving is learned, all a student needs to know is one route to arriving at the right answer. The ACT is multiple choice. How students add doesn't matter, only how quickly they can answer correctly. The new HiSET replaces the GED. I didn't care for the GED but compare it to the HiSET and you'll have a better idea of how tests may be changing. But keep in mind that I got a 29 on the ACT and yet struggled with some of the GED math even 10-15 years ago. Either I overthought it or it was simply very weird. So compare HiSET to GED, not HiSET to old ACT.
