Business Bellwork - What would you have invented?

I’m a huge believer in bellwork. Some activity for students to do/ think about as soon as they walk into my room. Sends out a signal. Lets get down to business.

On the IWB today I had a simple question. If you could turn back time, what would you have invented?

I had some cracking responses and you could really see the students thinking. No right answer, no wrong answer. Just a nice activity to get them thinking about business, which can’t be bad.
