I tried out the jigsaws mentioned in a previous post (The blank ones from Wilko). For those of you who haven't read it, I put 2 'messages' on it in German about 2 songs (opinions and reasons why) and gave it to my set 3 entirely male Year 9 class to work out in pairs. There was some differentiation in that 2 sets had single words on each piece, whilst the rest had words written across the pieces, thus making it easier to put together. It was a race to complete them and tell me the 'message'.
At the end of the lesson I casually asked if they liked it and out of 18 boys, 14 of them said they did - success!
Watch out Wilko; stock up on your blank jigsaws, I'm coming for them!
