>write a way to make a ten to solve 8+9
do americans really?
Dad doesn't understand.
A way to play a mental game to solve 8+9 is to "Take two away from the nine" give the 2 to the 8, making it ten. Then 9-2 is 7.
10+7 = 17 which equivalent to 8+9
Just because it's different doesn't mean its bad. When you see it you'll come round.
I had gone to a few middle schools and high schools, some used the engageny packets and some didn't. I failed every math class that used common core, and aced every single one that taught their classes differently but abided towards the standards. Most of the teachers that used the packets were lazy shits and didn't teach anyway. You can find these packets online at engageny, and all the answers.
you actually spell it "xyu" but close enough

>For example if you want to solve 121-93 quickly, you add seven to both giving you 128-100=28 which is much quicker to calculate. (or into 120-92=28)
>A kid that is talented at math would intuitively simplify 121-93 into that automatically inside his head. Common Core is a bad attempt at trying to transfer this ability into the heads of black children. Common Core tries to teach them things that they do not understand.

Ah, the ol' unreliable narrator trick.
>If you're halfway decent with arithmetic you do these tricks in your head automatically, without thinking about it and certainly without ever having been taught it. Forcing kids to learn these tricks in school is about trying to make everyone good at math. It's not gonna happen.
