I did this project with my grade 4s last year. That grade is anime mad! (and Miyazaki in particular) So I showed them some clips of famous Ghibli films. We then had to create our own creature and use oil pastel to depict the creature in a scene.
I did this one in preparation for a lesson with the Grade 3s. I asked them to imagine that they were incredible, scientific explorers and that they had found the most amazing creature ever! They first had to design this animal and label it, before doing a drawing of themselves with this creature.
