On Wednesday I tutored an Algebra 1 student who was just starting to learn how to solve 2 step equations (solve: 5x + 3 = 13). ... I've taught older kids for so long, and I just daily take it for granted that "my" kids can do that without thinking, that I forget how much they know and how hard it must have been when they first started out learning such things. It was refreshing and a nice reminder that everyone has to start somewhere, and it doesn't just come naturally.
Of course my precalculus kiddies were struggling today with:
Solve sqrt(x-5) - sqrt(x) = 7
Everyone is struggling at a different level. ... except for us perfect people (cough cough).
