For the students I teach, the textbook doesn't have enough practice problems that are simple enough. One, maybe two, then they're off to multi-step, challenge problems. I use KutaSoftware to fill the gap. I purchased Infinite Geometry a few years ago and I love it. (They're not even paying me to say this, but they totally should.) The free worksheets are great... but kids are smart. Mine figured out pretty quick that the answers are online. Is that considered cheating, or just using your resources? Now I just make my own. Problem Solved.
