I think it's brainstorming. I started the buzzer warm up in class, Mrs. Lamoreaux was going to ask us some questions. Part of these questions are about grammar and the other parts are about some topics for writing. We will have 5 minutes to complete the grammar questions or use the topic for free writing. I think warming up with the buzzer is like a game. It can not only help my brain continue to function, but also wake me up because this class starts early. I always felt asleep. Warming up the buzzer can also help me review my knowledge. I can find the kind of knowledge I had forgotten. Warming up with the buzzer is very interesting and is also one of the most important skills I learned in this
