Our district is on a semester schedule. We have two 9 weeks per schedule. Now that we are finished with the first 9 weeks how do we hide it so that the grades do not show in the canvas gradebook. For example in Powerschool the 9 weeks that we have finished does not show unless we click on it and nothing is added to that 9 weeks, we just start grades on a new screen. Also when we try to post grades to Powerschool it repost all assignments again although they have been posted already. Is there a way to change that?
