With my 5th graders today, I separated them into two teams and asked them to write down a list of things that they would have in their house in 2025, which basically gets them to write down every noun they know, and maybe some of the dumber ones learn something from the smarter ones, and they at least have fun because it’s a game and a competition.
I’d hoped they would think of all sorts of futuristic high tech stuff, but mostly it was just random nouns – TV, toilet paper, teacher. I said “In 2025, you will probably have robot teachers” and I was joking but I realized as soon as I said it how cool that would be and how many advantages a robot teacher would have in a classroom of unruly 5th graders. 
Just start with peripheral vision. And literal eyes in the back of their head. And perfect hearing, and the ability to process ten or twenty different conversations at once. When she says that he hit her first and he says that he was being good, I never know who to believe, but the robot would have the goods on them.
It could hear the mouthy, sarcastic, little brat at the table in the back making mocking comments, reach out an extendable robot arm in less than a quarter of a second, grasp the snot nosed little miscreant by the neck, just under the chin (with padded, safety gripperhands, of course, robots could do this sort of thing without any risk of physical injury), raise them up to the ceiling while their legs flail wildly and they (and the whole class) learn a lesson they’ll never forget.
Then, the teaching process could begin.

I just reread this and realize I sound like someone who read “Matilda” and sympathized with Miss Trunchbull. That is not entirely inaccurate.
