The first is a Video Spark Note - a summary of the entire play. This is just to help you keep track of what is going on in the play. Remember that in Shakespeare's day, the audiences would usually know the plot of the play before going to see it - so this is not a "spoiler"!
The second and third videos are the two Crash Course videos that you watched with the sub before the break (Part 1), and on the first day back from the break (Part 2). These are the videos you need to watch for the "Viewing Notes" sheet, which must be completed and handed in.
