Brainstorming Process

For my voicethread lessons I didn't really do much in the way of brainstorming. I looked over the website and tried to come up with some ideas (the book reading a writing voicethread). My dad and husband and I all sat down and came up with the other 2 ideas, we just talked about voicethread and looked at some of the videos. Fairly easy to do. I am not really too sure on how to do brainstorming :)
