Trying new methods in your classes is a great way to keep you and your students interested. My Google Reader now has over 100 great Math blogs. It is here that I often get inspiration to try new ideas.
Here is my worksheet following the same method. My Year 10 students enjoyed the game format and when I surveyed the class, 90% wanted me to repeat the game later in the year.
The format has a number of advantages:
1. Students are motivated by the game format.
2. Champion or Most Improved (using multiplying factor) winning categories are seen as achievable by all or most students.
3. Students pay careful attention to solutions to see if their solution is correct and hence they can add on points.
I introduced the rule that you must gamble a minimum of 5 points on each question. It soon became evident that some students were high risk players, others were very conservative. By question 5, one student lost all their points and begged to be allowed to borrow points from a friend!
By question 9 excitement was building. Bruce was well in the lead, then forgot to collect like terms! His explosion had now bought other players into a winning position. Kate looked to be the likely winner until she factorized x2 – 5x – 104 to equal (x + 13)(x – 8). Because of the impact these mistakes had, I don’t think these students are likely to make the same mistakes again.
And so finally Matt was declared champion and Angus most improved!
Thanks Sue for a great lesson idea!
