Mystery Number

Ms. Lirenman’s class in Surrey, British Columbia, is also learning about numbers up to twenty, so my class challenged hers to a mystery number Skype. We chose a number between one and twenty and they tried to guess what our number was by asking questions that could be answered with a “yes” or a “no”.

Their first question was, “Is it nine?” They were right!

Then we tried to guess their secret number. We had previously played the mystery number game in our class, so we knew some “fat” questions to ask such as “Does it have two digits?” but sometimes the temptation to ask “Is it four?” was just too much to resist. Finally, after lots of work eliminating numbers, we guessed it. We also let them have another turn because they were finished their turn so quickly the first time.

We had fun learning with your class, Ms. Lirenman! We hope we can do it again soon.
