Priority rules

I talked about the priority rules with my class and of course I wanted to do it in a fun way. I found a fun idea on NCM's homepage (http://ncm.gu.se/). I myself was taught something new. Saw this little "devil" to use to remember the priority rules easier.
The Devil!

Then we played a game with dice. A team of four pupils played with 4 or 5 dice and they would, with the numbers on the dice come up with as many expressions as possible. It would of course be solved as well. It became a bit of a contest and the winning team came up with 24 expressions made by 4 numbers. One rule was that any mathematical method could only be used once per expression.
