I teach a second group creative writing at a nearby school and don't have permission to share those children's work. However, I can tell you what we did today.
I took in a few lively stickleback from the pond and let the children examine them with magnifying glasses and chat about what they could see. As usual, they used this colour chart to note the exact shades on the fish's body. I read out the fish facts sheet and then asked them to write the numbers 1-10. Then we did a line-by line poem. My fish weren't quite in full breeding regalia because it's only March so I missed out number 5, but we covered everything else, and the pupils' ideas of what the fish might dream were especially good. A really nice session.
