Use AnswerGarden to Brainstorm with your class
AnswerGarden is an online interactive feedback tool. It can be used online or embedded on a blog or wiki. It is great for brainstorming with a class or having students respond to a prompt at the same time. It is free and can be used with students under 13. I like that it is minimalistic and easy to use. I like using it for opinion type questions and also for bellwork.
