A great tool that I was introduced to at ASU was Menti. Menti makes learning exciting and interactive. It can be used for multiple choice questions or brainstorming. In my example, I used it to ask students what they knew about graph shapes. This would be a great opener to a new lesson. It will provide me valuable information such as what knowledge students already have on the topic. I can ask the same question at the end of the lesson to see how much they learned.
