The odd one out game we were given for Christmas was no exception, so here it is, a Maths version of Odd One Out. The aim is for it to be used with ABCD cards either as an icebreaker or 'filler' at the end of the lesson. It enables students to use their knowledge outside of the context of the lesson on a specific topic, and involves all pupils as it is self-differentiating - each pupil can look for a different level of difference between the choices. On pressing REVEAL the odd one out and its reason is given, but naturally there are often perfectly acceptable alternative reasoning that students could come up with, making it very interesting to see the different ways in which pupils are thinking.
Questions are levelled from 1 to 5 by content (5 is A Level), with the 'questions' tab giving the list from which the game draws. Some of these questions look at the 'lists' tab to randomly select an option, keeping the questions fresh.
