I think there is a fundamental misreading of what it means to have a creative curriculum. This does not, and never has, meant sacrificing in depth subject knowledge just so things can be shoehorned into a 'topic'. I choose a discrete subject and then look for other areas of the curriculum that link firmly. So, for example, if I teach a theme based around Victorians, I might not teach any science, unless I feel it strongly fits, but I would teach literacy and art according to that theme. When I teach Earth and Space, I would expect to teach a more science and geography heavy curriculum becasue often, it makes no sense to teach one without the other. Some subjects are easier to include in every theme than others. It has to be a careful choice, not just for the sake of 'fitting it in'. Sometimes this means I have to teach discrete subjects alongside out majority theme - and that's fine!
