Mystery Number

Ms. Carlson's class tried a Mystery Number Hangout.  The mystery number is guessing a number between 1 -100.  You use yes or no questions.   

For example:
  •  Is your number greater than 50?   
  • Is there a 5 in the ones place?
  • Is it a 2 digit number?    
It helps to have a 100 chart so students can cross off numbers as you go.   For older grades, they could use larger numbers, but the hosts should probably set up the perimeters prior to the call.   

Ms. Calrson's class being mysterious!
