My daughter is 8 (and a half) and is growing up in Germany. I think it might be nice for her to have a penpal in Britain - have you already found someone or shall I ask her? She likes parties, reading, barn dancing, art and design and baking cakes. Big topics in her life are pros and cons of best friends vs groups of friends, why you can't just add 7+7+7+7+7 every time you need to know what 5 x 7 is.
My daughter had a couple of penpals at that age through Aquila magazine. You have to subscribe and it's not that cheap (thanks grandparents!) but they do a penpal page every now and then with kids age approx 7-14.
