Throughout the year, teachers will sometimes exchange classes for a unit or two. Since this schedule change isn't captured in PowerSchool, it means that those new classes won't be associated with you in any Clever apps, including ThinkLink. Mike and Jeremy are happy to add you as a co-teacher to those classes, but need some time to do so.
If you are going to be exchanging classes and would like to be added as a co-teacher in any Clever app, please email Mike and Jeremy at least a week in advance.
