Here’s a fun creative writing exercise that they use at my daughters’ elementary school: First the students draw a picture – it could be anything, let’s say a town square with shops and shoppers and a government building and street performers, perhaps jugglers or fire-spinners. Then, they cross out part of the picture, for instance the street performers. That’s the part that they describe in writing.
My daughter’s friend, who told me about this, said “it’s like pirate treasure buried under the X. You keep digging and digging into the writing and more and more is revealed.
