Greetings parents and students!

While the COVID-19 pandemic has limited our ability to have class every day, you all do have opportunities to review what has been learned throughout the year. Below, you will find an outline of the topics we have covered and specific resources that you and your child can access to review the content. 

Although PWCS is unable to provide instruction or class assignments to students while schools remain closed, our School Division hopes that the suggestions for optional learning activities posted here will help parents support student learning until schools re-open. Please remember that use of these materials and participation in these activities are optional and neither grades nor course credit will be awarded.

In addition to the specific resources listed below, review for all 8th grade content is available at the following websites:
