Number Numbness

I like math, I am comfortable doing math and figuring out basic math problems. So if I like math and feel comfortable doing math then why do I feel exhausted after doing math homework with my son. I try to not get frustrated with the process but I feel myself slipping at times. My son's school habits have a simple pattern, if you exhibit confidence in his work, he is very self-assured. If you start to descend, he tumbles into self-doubt. I need to recognize my descend before he starts to slip. When we are both climbing, its a beautiful thing.
