Then today's lesson (pdf) was briefly reviewing solving a system of equations by graphing, and then learning about solving a system of equations by substitution. We will talk more about the iPhone problem tomorrow.
Your homework for tonight is:
- Prepare for the Parallel and Perpendicular Lines Assessment tomorrow. There are a variety of ways to do that including, but not limited to: review the online pre-assessment; review your notebook and/or the openers and lessons posted on the blog; review the video, work some practice problems in your textbook or that you find online. You can, of course, also get help from me, another math teacher, a teacher in the Study Center, a peer tutor in the Study Center, or a parent, sibling or friend. Do whatever works best for you, but make sure you're prepared. The expectation is that you should all be able to do very well on this assessment.
- Complete the Essential Learning #3 Online Pre-Assessment on the Moodle.
- Review Friday's lesson/video (solving a system by graphing) and today's lesson (solving by substitution).
