Sounds plausible, but IME doesn't actually work with real kids
[It works to get class buy-in, even if you are offering meh choice A and awful choice B. A class that has chosen "A" will be more engaged doing it than if you just told them to do A...
but you'd better be ready to do 'B' if the class decides to be contrarian. Once, they really wanted to do the quiz to show that they really -do- know what we've been doing, and if I hadn't had the quiz prepped and ready I'd have been in trouble...]
Has literally never worked with my kids (now aged 17 and 13) fwiw.
Oh, totally. It does work with my kids somewhat, but there has to be at least a minimal reason for constraint and at least some desirability of the options. At school, constraint is expected and things that are not entirely fun are tolerated.
Asking A or B for breakfast as someone else pointed out, when they're not interested in eating, isn't going to do anything.
Also--my wife and I do the "A or B --- or -you- propose something" with each other. Prevents just absently saying "nah" to a long list of options.
I force a choice on mine, and she immediately 'strongly' choose the other one, which I reject, which makes her want it even more.
Me: <Kid's name>, do you want apple juice? No. Do you want orange juice? No. Do you want grape juice? No. Well that's all we've got, which one do you prefer? None, I want something else. ... and obviously whatever we had would not do. My mom who saw I was not efficient enough: Okay <kid's name> do you want apple or orange juice? Orange.
My first reaction was "but I already suggested it", but I got better after a while.
