Birthday Gift Ideas Needed

PresentsOK, let’s have a little group participation on this one. I need to get a birthday present for a classmate of my third-grade son. The boy is friendly enough to invite my son to his party, but not in the “best friends” category. I’ve never met the boy or the parents. Other than “Star Wars,” my son can’t think of anything the other boy is into. Any ideas?

It was easier when they were younger, and a box full of art supplies would suffice. Now, I feel pressure to get something the other boy will think is “cool,” since I know my son will want to be seen as a giver of cool presents. I hate to fall back on Legos, cool as they are, since I don’t know what the other boy might have already.

Can any of you please give me a hand here and share ideas in the comments? Leave ideas for other ages, too—someone else might find them helpful. Thanks!
