How do you deal with a sister that asks for help very often?
Allocator2008: Just say, "Well, how would YOU approach this?" to gauge where she is at. So rather than solve it for her every time, have her give it a stab first. Let her be totally wrong, but at least have her try. Then correct her approach and set her on the right path. Then if she really is stuck after making an honest effort, then help out with the answer, but basically the more times questions like "What do you think?" are put to her, the more she will hopefully think on her own.
