Popplet is an internet site which helps you to create mind maps easily and simply, around any subject you like. There is a youtube video to show you how to make a popplet and this one includes the use of it in an english lesson.
I have made a Popplet on the use of ICT in Early Years and Key Stage 1, which i will be updating throughout the course.
I think a Popplet would be a good resource to use when starting a new topic which children on an interactive whiteboard. The subject could be put into the middle of the screen. Then, in one colour coming off one side, information the children already know could be added. On the other side in a different colour could be things about the topic the children want to find out. There are endless ways this resource could be used in Early Years and Key Stage 1 Education.
