Today we began with our assessment over Solving Equations with Variables on Both Sides and then created the key (pdf). I reminded you that the key would be posted to the blog and that you should check your results on the portal and sign up for re-assessment if necessary (see below).

We then explored graphing by using a table of values and an application problem involving recursive sequences, equations and graphing (lesson, pdf).

Tonight's homework is:

1. Check the portal for the results of your assessment, fill out your student checklist with your results, and make a plan for re-assessment (if necessary), including making an appointment. Many of you have unscheduled hours on Thursday (tomorrow) - please make an appointment and come in tomorrow if you need to re-assess (or get help and then re-assess). You can also come in during part of your lunch if necessary as the re-assessment should take only 5-7 minutes (still leaving you time to eat). Please don't put this off - the sooner you come in, the better.
   
   
2. Please finish the graph we started in class and bring it with you on Friday (it should look somewhat like this (pdf)).
   
   
3. Watch and complete the Graphing Linear Equations by Using a Table video. (You know what to do, and what to write down in your notebook and have with you on Friday, right?)

Today we began with this exciting opener (pdf). We then practiced solving two-step equations and explored some more complicated equations, including equations with variables on both sides (lesson, pdf).

Tonight's homework is:

1. Watch and complete the Solving Equations with Variables on Both Sides video. (You know what to do, and what to write down and have with you on Monday, right?)

Today we began with this brilliant opener (pdf). We then learned about solving two-step equations by "undoing" or doing the inverse operation (lesson, pdf).

Tonight's homework is:

1. Watch and complete the Solving Two-Step Equations video. By now you should know how to watch these videos effectively, and what you need to write down in your notebook. (But, if you've forgotten, please look back at previous posts to find the instructions.)
   



2. If there's anything you need to get caught up on, please do it. If there's anything you're struggling with, please come see me and we'll figure it out. All of you have at least one unscheduled hour tomorrow, so I expect you to come in if you need help with anything in my class.

Today we began with this scintillating opener (pdf).

We then spent some time talking about direct variation (lesson, pdf).

Your homework for tonight is:

1. Watch the Solving One-Step Equations video (choosing to watch it full screen is probably best).
   
   
Recall that there are three main parts to the video: an examples and explanation part, a Guided Practice part, and a Self-Check part. Examples and Explanation: Just what it sounds like. I explain how to do the problems and work through some examples. You don't need to write anything down (unless you want to), just watch, listen and learn. Pause the video and replay parts if you need to. Guided Practice: I give you a problem, then ask you a series of questions with about 5 second pauses between questions for you to think about it and answer it for yourself. If you need to, pause the video to give yourself more time. Again, you don't have to write anything down here (although you can and it's often a good idea to). Self-Check: I give you a problem, ask you to pause the video, write the problem down in your notebook and solve it, then play the video again to check your work. You may need to pause the video again to view the solution if you need more time. These problems you definitely need to write down in your notebook - I'll be checking to make sure tomorrow.
2. Can you find a direct variation in your own life? 10,000,000 points of extra credit if you do*
   (*extra credit valid only on days that don't end in a 'y').
   
   
3. Remember that Wednesday is a PLC Day - late start. Our class begins promptly at 9:21.
