I was inspired by Elementary AMC to make a "What's the Question" board recently, but I wanted to take it a step further!
I started with the plain board (I plan on sprucing it up with some border once I get it to its permanent spot). First one to spot my mistake gets a virtual cookie. :)
Next came the Answer & Question pages:
After that I came up with a few other open ended questions that I often ask my student as a warm up or to add in their journals.
The beauty of this poster is that you can write anything you want on it for your students to respond. I often use it as a "Exit Slip" board and have them answer one question as a quick assessment. This poster could carry across into other subjects as well!
I have made these into a free product on TPT.
