Christmas present for my aunt with kids photo ideas?

So i know its not that close to Christmas yet but I like to get the job done early. Anyways my aunt has three kids ( two boys ages six and eight, and a baby girl about 18 months) And I have a Nikon D5000 and I was thinking to take the kids to my grandmas house when there are more leaves on the ground and take cute pictures of them and then get a cute multiple picture frame for the pictures and thats the present… At my grandmas house she has a pasture, sheep, goats, chickens, a minature horse, and a tire swing, playground set up. So what could I have the kids do? Got any ideas?
