# Algebra 1 6/8/15

For each video, there are questions that follow.  In order to get the assignment from the sub, you will need to show her that you have answered the questions on your own paper.  All of the answers will be found in the short video.  Remember that you can rewind and replay as needed!

We will review a little bit in at the beginning of class tomorrow, but you are still responsible for this information on your own!  I expect you to actively watch each video.  This means
*Avoiding other distractions (no music/games/videos in the background).  If you have
other things going on over the sound of the video your brain will not get all the info it
needs!
*Taking notes.  You are not a computer and you will not automatically learn
something just from hearing it once!  You need to write it down.

We will take a quiz tomorrow, as always!
