Adding & Subtracting Radicals

I teach 3 different classes of algebra 1 preAP. My poor 1st class gets all my mistakes and things I test out. My 2nd class gets the refinement, but still not "the best" I'm going to offer this round. By my 3rd class, I've had time to mull over ideas and see what works and doesn't work and anticipate their problems. So... Here's the 1st page of what my 3rd class is going to get on Monday when we learn adding and subtracting radicals. You don't even want to SEE what I subjected my 1st period to. (here's the whole 2 pages).
