I'm not familiar with abstract math as 2+2=4 has worked well for me.
I had issues with Algebra in middle school and had to take summer school to progress. Blew it off as I didn't know how that would have any effect in my future life and the teacher couldn't explain it to me how it would. It was just a rote system she used to teach.
Amazingly enough later on in life after high school, algebra became my life as well as geometry. I hated both because the teacher could not relate to me how it would would benefit me later in life.
Teachers should teach what their subject can do for the student. Not just teach 2+2=4
Sadly most teachers cannot and have not experienced life like the rest of deplorables have.
I use relatable concepts to get buy in all the time. It's one thing to tell people what they must do, but another entirely to see the light bulb go on in their eyes and truly "get it". I never really got that from the majority of my teachers. Most of what I've learned is self taught or what I saw others do.
