Thanks for mentioning the lack of base 10 teaching. I am shocked and disheartened by that…it is the structure of our entire number system. I have a little series of math tutorials here on Medium and one of the first things I cover is base 10 and base 2. It is such an important concept!
CC definitely needs improvement. I love that people are pointing out specific problems. If we can create a discourse to educate people on what needs improvement, instead of people arguing with each other, maybe our collective voices can be heard and improvements to the system can be made. It’s worth a try anyway.
