Last week Peterborough had its first Maths Jam. Amongst all of the maths puzzles being thrown about, a few of us settled down to exercise our minds by playing a nice game of SET cubed<\/a>. Those of you who are new to SET, it\u2019s a game of connections. There are many variations to the game, but the main objective in all of them is to be able to complete a set of 3 cards. A set is a set when..<\/p>\n For example,in the following the first three cards are a set as they all have<\/strong> a different number of items on each card, they all have<\/strong> a different symbol, they all have<\/strong> a different colour and they all have<\/strong> a different type of shading. The second group of 3 cards are also a set as they all have<\/strong> the same number of items, they all have<\/strong> a different symbol, they all have<\/strong> the same colour and they all have<\/strong> a different type of shading. Finally the last group of cards don’t form a set as we can’t say “they all have” about every property.<\/p>\n <\/a><\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n <\/p>\n A good place to get started would be to visit the website setgame.com<\/a>.<\/p>\n Anyway, having renewed my excitement about SET (I went through a phase a few years ago where I had downloaded the game on my iPhone and played it for hours!) I wondered how I could introduce it to my students. I wanted to do it in a way where I didn’t have to “teach” them anything so I put together a powerpoint<\/a> and found a set of cards<\/a> that I printed off. The first slide uses just one colour and just one shape.<\/p>\n <\/a><\/p>\n I shuffled the 9 cards and asked a student to pick out 2 cards at random. I then held these up and the students had to write down the grid reference of the card that would complete the set on their miniboards. I gave them\u00a0absolutely\u00a0no instruction about what would make a set, they just used their own intuition. This led on to some beautiful whole class discussion and we then slowly built ourselves up to the full set of cards. All of the students were able to complete any set I threw at them and I had given no instructions to them at all. \u00a0It really was a fun lesson activity and we used the SET website to do a puzzle of the day to finish off our short session on this. I promised them a revisit later in the year and I may buy a few sets of cards<\/a>\u00a0to use in class.<\/p>\n Some interesting tasks might be to ask..<\/p>\n\n
