My children were a little scared of the idea of the catacombs, so we didn't do that at about that age.

The did like walking up the Arc.

They also got a small kick out of the metros.

They/we liked Château de Vincennes.

Invalides can be tiring and maybe more for a boys' taste, but the armor and weaponry can be fun to see.

Rodin nearby may not be that interesting to her, but it has a nice outdoor space.

Second vote for Jardin du Luxembourg -- our hotel was near there and our daughters LOVED it. Even though they're older than your son, they would want you to know about the incredible little playground there. It costs a few Euros (I think that's all-day access) but they said it was one of the best playgrounds they've visited in their life.

Here's a link to our Paris album which includes some images from Jardin du Luxembourg.

*correction -- older than your daughter. Sorry about that.

Perhaps the Montmartre Funicular?

I'm a photographer and when my son was about 10 or 11 I used to take him to Paris when I had to work there. One of the things I did was to buy a whole stack of disposable cameras for him and have him photograph to his heart's content. I bought the Ilford FP5 ones, so his photos were all in artistic BW. He photographed lots of buses and intersections, and it was fun.

menachem - yeh I thought of that too - my son at that age had a great time there.
