Wii for Mean, Mode and Median – The Outcome.
I thoroughly enjoyed our maths session on Monday, using the wii and I think the children did as well. As ever, I’ve learned a few things which would lead to a few ‘tweaks’ if I was to do it again. Before I discuss those I must say the P7 children are all far better ten-pin bowlers on the wii than I am and had a range of entertaining styles all of which proved to highly effective!
The lesson had a sparkle to it to begin with as the class noticed straight away that the wii was set up. ‘Are we using the wii in maths?’ was a popular question!
That moved on to ‘We’re not using brain training are we?’ which I found interesting and probably reinforced the point that just having a wii on for maths isn’t enough. It needs to be properly targetted and integral to the lesson, not just the lesson itself.
We formed our teams and each team played out their first frames, and we got used to recording our scores. Bowling is good for this, as you can pause between throws to make sure everyone is up to speed.
On the second frame I introduced the idea of modal average. The skills on show ensured that we quickly identified 10 as the modal score. The class found this quite easy.
After the third frame for each team we introduced the mean average. We needed a bit of calculation help on this to get the division by 12 done. We also spent some time working on rounding to 2 d.p.
After the fourth frame we began to find the median also. In hindsight I shouldn’t have had 4 teams, as it meant we always had an even number of scores to find the median for, and this made understanding of this concept harder.
We carried on and completed the game. I changed my idea of getting the averages onto the board and adding on points as I felt I didn’t want to pressurise the groups too much! We also dropped finding the mode after 6 frames as it was always going to be 10!
In summary the class and I enjoyed it, the lesson had an exciting feel to it and I feel the children learned the objectives I had for them at the start of the lesson.
