ah yeah, they're doing things by 5s and 10s. yet another
experiment in math education. If you read the common core stuff,
they don't bring the kids back to the math *we know* until about
the end of the 8th grade. All the confusion is supposed to
restructure the brain or something and teach "Grit" by making
things slow and difficult on purpose. It's all because of a pop
psych book on Grit that got popular a few years ago in education
circles and became "A Thing".
It won't last more than a few years I bet; most of these
experiments don't last more than a few years. When my nieces
were in grade school here in FL, it was "leafs + nodes" - some
abstract university level concept that was impossible to find
info on the internet about. afaik, they've scrapped it since
then.
By the time Sylvian Learning Centers has shortcuts to teach kids
this stuff - just like they had shortcuts to teach kids our kind
of math, they'll scrap it for something else and meanwhile, yet
ANOTHER GENERATION of kids will grow up thinking "they don't
know math". Ugh. Yeah, I could rant about this for days.
In the end, they just found YET ANOTHER WAY to make school suck.
