This is you first official homework assignment. Some of you may not have access to a computer at home and thus will not be able to watch this youtube video from school. You have an alternate assignment. The assignment is to watch the video and be ready to answer questions when you come in to class.
If you are watching from a school computer then you must go to vimeo.com or gaggle tube. Once you are at either of those sites then simply search rational and irrational numbers and watch a video fo your choice. Make sure you understand the concept when the assignment is due.
