What, the two of them staying together in the frame and seeming to actually like each other?? lol Crop them down a little and you've got a couple of nice pictures.
I've been a teacher, it takes using something to get them to look or get their attention - depends on the age, some little props or toys, making a noise, saying something funny, etc. And the timing, wait a second... another second... til they're both looking. Take more than one shot. Kids are not usually likely to stay there long so you need to be prepared and work fast.
