You can move a lesson activity anywhere you would like. You can move it up, move it down, move to previous day, move to the next day or move to homework.
To move an activity, click and drag the activity to the location you would like it to be and then let go.
You can also move an activity to the next (or previous) week in the Lesson Plan, by hovering at the edge of the current week.
You can also move all Lesson Activities on a day over, by Adding an Empty Day into your Lesson Plan. This may be useful if you didn't get to everything planned for a day, or if class is cut short or canceled unexpectedly.
