Here is a quick craft idea for you.. why not print out some Olympic Pictograms such as the below from Buyong.com, print them twice on card (or coloured card to brighten them up). Cut them up and hey presto – you have an Olympic Memory game! And you can practice talking about all the different sports to your children too! (Please visit Buyong.com if you want to use the image).
If you specifically want the London 2012 Olympic Pictograms, I found a copy of them DSGNWRLD.com:

My favourite are the ones from Munich 1978.
Just do a google search!
Happy Olympic Crafting!
