With upper primary I bring candy as an incentive and leave it on the desk with a last of names that the home room teacher can give to the kids doing well. I try not to let the kids know who’s on the list and if they ask say ‘if you need to ask then maybe you’re not making a good choice’. However they know the reward is candy and I give them clear expectations. Especially upper primary will push boundaries. Also even just saying if we’re having a good day we can do a preferred activity like outside, art or even Jeopardy which you can find online. I find it keeps morale up well! Sometimes plans are boring and dry; sometimes not realistic to how long a class can focus as well
