In your My EP Assignments account, on the STUDENT’S page, subject boxes start off dark yellow. That’s how they look before you click the Lesson for that day.
When you click on “Lesson Number ___” or the down arrow in a subject box, it will take you to that day’s lessons. The subject box will turned light yellow to show that your student has started their lessons.
Later, when the parent checks the student’s work, the PARENT can either click the green check mark to mark that lesson complete or the red X to indicate that more work needs to be done. Clicking the green check mark will make the box turn white and dim the subject name and lesson number.
Here’s the video of the same directions.
