How to Answer EVERY Student's Questions

How do you acknowledge and answer every student's question, every day?  You may be thinking it's impossible with all the time restrictions and curriculum requirements, let alone the sheer number of questions students ask each day. Believe me when I say it is possible, and I'm here to share how!

Allow me to present my "Burning Questions Board". This one bulletin board has single-handedly cut down on unrelated comments/questions and helps nurture student wondering/creativity.  

Students write their name, date, and class period on a slip of paper, along with their question or comment.  Then then put the slip of paper in one of the library card pockets.  

I check the pockets on a daily basis or each class period if I have time.  If it's in relation to something we're currently discussing, I try to answer it on the spot with the whole class. 

If it's a question I don't know how to answer, I might assign it to my student researcher, who will use an approved device/search engine to find the answer and share that information with the class. 

If it's a totally unrelated/inappropriate comment or question, I may discard it or put it aside to address later.  If I keep it, I will write a comment on it that lets the student know why it wasn't addressed publicly. 

Do you have any tips on how to make students feel validated when they ask questions without taking up to much time?  I'd love to hear about them!
