Instructions:

Each child has one cardwith a calculation on it. They have a short time to work out their owncalculation, then they all have to stand in a linein thecorrect order, highestanswer to lowest answer. So not only do they have to work out their own answer, they have to work out lots of others too!
It is done in silence, it involves moving around, it's challenging, it canbe used for anymathematical calculations, and the children love it!
