Try to identify what pieces of the work are the most challenging or frustrating. Is it the amount of work, the level of difficulty or the amount of time? There are other potential challenges as well, but once you have identified the specific area that is most frustrating, you can address or modify that part of the work.
Always validate the frustration, ex: “I can see you are frustrated with how much time you are having to spend doing ____. Would it help if we did 5 more minutes, then took a break?”
You can also offer choices of which work to complete. For example, “Would you like to do math or reading?”
You also can refer to a reinforcement system if you have one in place.
