Mystery number / Math riddles


We are now into May. which means the end of the year is quickly approaching. Over the next few weeks I will be cluing up the majority of the curriculum, which left me thinking about fun review activities. I like to see my students engaged in the learning process in a unique and innovative manner. I also want my students to be accountable for their own learning - therefore I turned to Google+ yet again. My thought is what if my students created math questions/riddles and asked other students to find the answer and vice versa. The response I got from the google community world was overwhelming. Instantly I had 9 classes jump on board with my idea. Unfortunately finding a class in Canada has been extremely difficult, but regardless we will make it work! Using google docs, we've created a list of strands and topics that we've covered this year. Each class will create a question for a specific strand. During a combined google hangout, our classes will ask their question and then share the answers. In order to use the time in a constructive manner, we are also incorporating our class blog site.

Today we completed the first of 2 Mystery Math activities. We connected with a class that we previously completed a Mystery Hangout with. It was absolutely fantastic! The students created math questions "Which Number Am I?" During the hangout, students had an opportunity to read their clues, we also had the questions on a google doc to use as a visual. Our students used hundreds charts, base ten block app on the ipads and a partner to solve the riddles. 


Here is an example of a question we created:

My number is between 100 and 200.
It is an EVEN number.
It is more than 140.
It is less than 180.
The number in the tens place is 7.
My digits add up to 14.



An example from our pals in Alabama: 
My number is between 20 and 60.
It is an EVEN number
It is more than 25.
It is less than 35.
The number in the ones place is 4.
The digits add up to 7.
