At 3 and a half, it is probably a phase. Try giving her other things to do when she becomes angry. Things like jumping rope, throwing a ball, something physical to reduce the amount of frustration and to relieve her stress. Another thing you could try is giving her choices of what she wants to do. Two at the most, you can yell and growl in your room if you want or you can help me do the laundry, she will probably choose the first, but eventually, she will learn that it is more fun to be with someone doing something than to be upset by herself.
A little about me: I am a mother of a 7 year old little girl and step mother to a 22 year old. I raised the older one since she was 5 and she had many of the same tendencies, that is to become angry and "develish". I also work in a pre-kindergarten with some emotionally disturbed children. Your little one sounds like she is just being a normal (all be it demanding), little girl.
