Mystery Number!

http://www.abcya.com/interactive_100_number_chart.htm

Please check out this link to an interactive 100 chart! We have been using it in class to play "Mystery Number" and it is SO much fun!

One person picks a number between 1-100. Other players must ask questions to narrow it down, and guess the number. The only answers that can be given are yes or no!

We have learned that some questions can eliminate lots of numbers, and some only get rid of one.

For example, if we ask...

"Is your number 54?"   - That only gets rid of one number!

But if we ask...

"Does your number have 3 tens?"   - With a "no" answer, that would knock out 10 numbers!

And if we asked...

"Is your number odd?"   - We are getting rid of 50 numbers with one question!

Have fun playing!
