Brainstorming Race Brainstorming Race is a fun Google add-on where the teacher can give temporary write access to a document. Students can quickly collaborate and generate a brainstorm list. As soon as the time is up, the students can no longer write on the document. The teacher can then highlight the responses and create an instant Google Form so that students can vote on their favorite response. This is a great way to engage in an interactive lecture. Believe it or not, a developer came up with this idea in collaboration with his/her child. What a great idea! Here is their tutorial if you are interested in an overview . The only trouble is the time and effort it takes to share the document with the students. You would need a list of usernames to copy and paste when you are ready to share the document to streamline the whole process. Then you would need to figure out how to share the link to the Google Form with them as well. Share to Classroom to the rescue!!!
