Original Problem: Solve the system of linear equations by graphing.

Revised Problem: Draw a system of two linear equations with a solution of (3,2). Give the equation of each of your lines. Explain what the solution means. Show how the solution relates to your equation.

Open-Ended Items

Original problem: Evaluate the expression when x = 2 and y = 4
3x - 5y

Revised problem: Write an expression using the variables x and y so that it equals -4. Use x = 2 and y = 5 when evaluating the expression.

I agree with the article about open-ended items. The suggestions seem relatively easy to incorporate and finally, I feel that students will be thinking.

Attached are some assessment tasks covering a variety of Algebra 1/2 topics and how I have revised them according to the article, "Open-Ended Items Better Reveal Students' Mathematical Thinking'. Open Ended Questions.doc

I reviewed the Algebra Tiles activity. The first time I used Algebra Tiles was during the last class session in January. If a student was not familiar with the procedures and "rules" of using the tiles, I can see where the tiles would complicate the learning. I know that my district has the tiles but they are not used on a regular basis. If I were to try to use them at the high school level, after the students have been through years of math without them, I think it would create chaos and complicate the teaching. The tiles would be incredibly useful if they were incorporated into a math program and used consistently.

Can anyone clarify what the homework is for the February session? I cannot locate the "Open-Ended Questions" article.

Just got done doing one of the on-line chats. I found it very fascinating and informative. It included 15 people from all over Michigan. Well worth it if you have time to do one.

I really liked the activities on inverse variation. At first I thought that I might want my entire class to do the same activity, but in hindsight, I think that it might be interesting to have different groups do different activities and then report on what they found. Similar to what we did in the session. Unfortunately, I am not currently teaching Algebra 1 so will not get a chance to implement this. I would love to hear from anyone who did implement any or all of these inverse variation activities from the beginning of session VI. I am also curious how Algebra 1 students do with the Airport Impact Study activity. I found this a bit confusing and am not sure how 8th/9th grade students would handle this.

The most challenging part of the activities in the Learn and Earn CD was keeping up with the movie at times. Several times I wanted to just go back a little bit to relisten to a particular section, and I could not get the movie to do that. I had to restart the movie from the beginning each time. My learning experience reminded me of the activities in the A4A series as I was immersed in reframing some of my own thinking. Being the student in this activity, I felt engaged and found myself wanting to know more at each section. I thought about how I could incorporate some of the teaching techniques into my own classroom so that I could build proficiency in my students' use of the graphing calculators that we have to use. I also found that I as I worked through the activities, I gained more confidence in my own abilities and feel that the Algebra for All acitivities also build confidence in my students. Great activity!

I found the Learn and Earn very easy to work through. I finished it in about an hour and took the quiz. I received a confirmation that I had completed everything and that I would receive my log-on information in about 2 weeks. I thought that the movies were very helpful, and I really liked that I could work side by side with the movie. I really appreciate having the TI-Nspire and have been super motivated to have my students work with the graphing calculators since having my own.
