Can I suggest doing some activities around the theme of fairytales (if your dd likes that sort of thing). I teach in Scotland and we (primary one) are doing a project on this at the moment and its terrific! Loads of things you can do from any and every fairytale that takes your fancy, and these are stories that are not hard to get hold of, either from a library or online. If you google any of them you will find loads of stuff. In Scotland this is a well-known theme to do in P1 - and is usually started by a "dragon" leaving a letter saying that Fairyland has disappeared and can the children help to restore it. Obviously you are in a different scenario to the classroom but I wondered whether it would grab your dd's attention?
Are you or your dd able to use a computer at your mum's house? If so, I'm sure people will have lots of suggestions for internet-based activities as well as things you can download and print. What does your dd like?
Good luck! This must be a very difficult time for all of you.
