This is an excellent idea. The stimulus of Kensuke’s Kingdom is fantastic and is sure to bring about creative ideas and engagement. You have also covered the subject of mapping in geography in your scheme. The students will find mapping their own islands very interesting and fun. I think that this project lends itself to the students having great ownership and creative control in their builds which is fantastic. These projects should be Child led and this is clear here. The idea of a fly through video is also very good. I think the students would really enjoy this. they could use the fly through to then create a voice over script discussing the reasons for each building. Well done.
