Then we continued working on the iPhone Rate Plan lesson (pdf).
Tonight's homework is:
- Prepare for the Solving Systems of Equations by Graphing Assessment. 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.
- Look back over the first part of the iPhone Rate Problem. Check your email for the solution to the first problem we worked on (just minutes) and make sure you understand it (or come in for some help). Then briefly look at page 5 of the lesson (pdf) and see if you can figure out how to start the problem (we'll spend more time on this in a few days).
- Watch the Solving Systems of Equations by Substitution video.
