Deal or No Deal
A clever way to teach mean and median, based on the popular TV game show. Choose to play with between 1 and 22 boxes.
Pick one student as the main player – the other students can be asked to calculate the mean and/or median after each round of box opening (which can then be checked by clicking onscreen boxes) and use this to decide on a suitable banker’s offer.
To install unzip the four files to a new folder and run index.html – there
is a readme.doc file where you can find further information and teaching notes. (Note: I had to change my security settings in Internet Explorer v7 from medium-high to medium).
