in/at/on/over/during/last/this (the) weekend

[Topstudent]

Let's say it's Wednesday. I meet with my friend, who's a divorced father. I know that he sometimes sees his kids, who live with their mother, for a few hours at some point during the weekend. Which one of all these would be the most natural thing to say for an American?

Did you see your kids in/at/on/over/during the weekend?

Did you see your kids last/this weekend?
