My advice, although virtually no one bothers following it: Teach your kids reading and math PROPERLY (i.e., traditional math and phonics), and get them 2 years ahead and keep them 2 years ahead. Then, when your kids are told in school, for example, to 'diagram' 3x5, they will already know the answer and with that information they can play the Common Core game with their teacher and probably get the problem 'right'.
Of course the best advice is to simply get your kids out of the public schools...but then what the hell do I know about it?
Imbecilic.
What happens when you “have to work it through” when there are 5 equations, 5 limitation factors and a dozen other possible endcases involved in one problem ?
Maybe its a formula for a population being fed a communist style election (only one name on the ballot) ???
the 3x5 3+3+3+3+3 5+5+5 lesson example is usually eliminated after it proves to the student why it works, and thus becomes an accepted assumption so that more complicated things can be moved on to.
Teach them Algebra, which is the closest to Commie Core Math. It’s what my husband a Math Major taught our grandson.
The problem described here is not math, it is arithmetic
The entire program is insane.
Homeschool your kids!
