I am going to throw this question out to all of the panelists.
I think a lot of our audience on Cake are not educators. They may have done well in math during their undergraduate or graduate studies. They may even be recreational math enthusiasts for problems like these from @1to9puzzle .
But that doesn’t mean they know how to teach it to young minds. Let alone higher maths.
I know @amacbean16 is an accomplished homeschool educator, but assume for the moment that she was looking for specific ideas to introduce higher maths to both her 6 year old and her 6th grader.
What are your suggestions?
