5. grade school common core - how do I come up to speed?

I've tutored high school kids in traditional math classes such as algebra, precalculus, etc. I just was asked to interview for a long-term job tutoring a 7th grader in common core math. So before I go for the interview I want to get an idea what I'm dealing with, in particular any "strange...
6. Curious about high school factoring

When we have a quadratic polynomial of the form: ax^2 + bx + c WHY is it factored in such a way that the newly split b term MUST MULTIPLY to make ax^2*c? For example, if we have 4x^2+4x+1 , 4x^2 +2x+2x+1 =2x(2x+1)+ 1(2x+1) =(2x+1)^2
7. College math courses to teach high school AP CALCULUS well?

8. Simple middle school Parallelogram problem

In the bottom Parallelogram it is given that AD=20 and that the perimeter is 140. (Ok so therefore AB=DC=50). It is also given that AS=AM+18. We need to find AM, therefore AS and then to calculate the area of the Parallelogram which derives from finding AM. Now, I managed to find the right...
