Mystery Number Skype

Mrs. McKenzie read this post by Ms. Cassidy in Canada about her class doing a mystery number skype, and thought that the students in B4 would enjoy doing it too.
Now we've had our first mystery number skype with Miss Revell and her Year 2 class of iKids, near Napier, New Zealand.
Beforehand, we brainstormed some useful questions, so we could eliminate lots of numbers from our choices.
These questions can all be answered with 'yes' or 'no' answers. They are called skinny questions!

First, our class had to work out their mystery number.

After lots of questions to eliminate the numbers, there was only one number left. It was 64!
That meant that the iKids won that round!

Then it was their turn to guess the number we had 
chosen to start with, which was 67. 
It was funny that both classes had chosen a number in the 60s!
For the next rounds we tallied the number of questions asked. Both classes solved their puzzles in only 6 questions.


Now we are looking forward to more mystery number skypes with Mrs. Watson's class in Canada; 
and Ms. Lirenman's class, also in Canada!

We have a mystery number for you to work out.
Ask us questions in the comments section.
Remember, questions can only be answered with 'yes' or 'no'!

    Thanks for your Skype call! It was funny when we both chose in the '60's when we were doing the mystery number Skype. I was a little bit excited when I got the last number.

    Is your number 24?

  2. Hi Open the Door to B4

    I do think that it is a bit funny that both of our numbers were in the 60's. Is your number between 50 and 70?

  15. Thank you for joining in the mystery Skype number game.
    While there is no one way to do a Mystery Number Skype call, we’ve now done about a half dozen of them and this is how we have found it to work best.
    1 When we are getting ready to play mystery number Skype, everyone, including the teacher, writes the numbers up to 20 on a small whiteboard. (We got this idea from Karen Lirenman’s class during our first Mystery Number call.) Paper or a drawing app on an iPad could also work.
    2 Each class secretly chooses a number between 1 and 20. We usually do this before the call as well.
    3 Each class asks questions with yes or no answers to try to guess what the other class’s number is.
    4 For our purposes, we have one class guess until they get the correct answer and then the other class guesses. For my young students, this has so far worked the best.
    As the students determine which numbers have been eliminated, they cross them off or erase them from their boards. I do the same to help those who are still unsure of their numbers (or who were distracted and missed something). Besides being a great way to practice identifying the numbers, it keeps all of the students engaged during the call.
