In early February, we will be taking the California High School Exit Exam (CAHSEE).
You received a copy of the math study guide on the last day before break. If you lost it or did not receive it, you can obtain a similar copy from the following link:
http://www.cde.ca.gov/ta/tg/hs/documents/math08rtq.pdf
Complete the following and turn it into be by January 14th (the end of intersession). If you will be at school the first day of intersession, you can provide a handwritten version of your work. If not, then you will need to scan or type your responses to the following. You will not turn in the booklet but your responses on separate sheets of paper.
1) Complete the practice text and identify areas that your may need to practice. I need your answers and a reflection after your graded it about areas that need improvement. (NOTE: for the practice text only, I only want your answers (A, B, C, D) rather than your work)
2) Read through each of the six chapters and complete the sample questions at the end of each chapter. Provide your answers, your work to solve the problem (when applicable)and a reflection after you graded your answers for each problem.
For complete and thorough responses, you can receive 2 points for the practice text and reflection, and 1 point for each chapter resulting in a total of 8 possible extra credit points.

Welcome 2009/2010 Students
Hi guys,
If you are on the Duffy/Lopez team for 2009-2010 and you are looking for Anne's blog, you are in the right place. I am using the same blog as last year so only things posted from August 2009 will apply to you guys. That being said, you are welcome to look at past blogs. There is nothing secret about them including the fact that I will use the same or similar wording as earlier posts to assignments that apply to you guys.
I am glad to have you on our team. This is going to be a great year!
Anne

Molarity homework
A student makes a solution be dissolving 3.942 grams of AgNO3 (silver nitrate) in enough water to make 100 mL of solution. She labels this solution “solution #1.”
She then takes 15 mL of solution #1 and dilutes it to 25 mL. She labels this “solution #2.”
She then takes 5 mL of solution #1 and dilutes it to 50 mL. She labels this “solution #3.” Finally, she takes 10 mL of solution#3 and dilutes it to 100mL. She labels this “solution #4.”
1) Draw a sketch of the relationship between all of the solutions paying attention to which dilution was made from which solution.
2) Calculate the Molarity of each solution. Be sure to show all your work with the proper units.
3) Categorize each solution as either “original stock solution”, “dilution of stock” or “dilution of dilution.”
She then takes 15 mL of solution #1 and dilutes it to 25 mL. She labels this “solution #2.”
She then takes 5 mL of solution #1 and dilutes it to 50 mL. She labels this “solution #3.” Finally, she takes 10 mL of solution#3 and dilutes it to 100mL. She labels this “solution #4.”

Anne update and a call to step up
Hi guys,
I wanted to give you guys some info on what is going on and ask you to step up and make me proud for exhibition.
My grandfather passed away recently and I flew out for the funeral. My grandmother has dementia meaning that she does not remember most people most of the time, sometimes doesn't realize that her husband is gone, and has a grumpy time in the afternoons. My aunt is going to take care of her at her home in Idaho. I will be helping my aunt drive from South Carolina to Idaho with my grandmother. I am not sure how long it will take exactly because days with my grandmother are unpredictable. My plan is be back before exhibition- but it might be JUST before exhibition night.
So this is my "assignment" for you guys. Own this exhibition! Don't wait for Paul or another adult to tell you what to do, make this YOUR exhibition. You know what needs to get done and we have committees set up. But if you are not on a committee, please step up and help where needed. Make me proud of you guys. Rather than see any downtime as addded social time with your friends, grab your friends and get stuff done and ready for exhibition. Help Paul make a list of things to do, complete things on that list and go out of your way to make this project POL the best it can be. My biggest concern is finishing the shoe project and getting those on the wall. This is a BIG part of the evening and it will need many hands to make it look good.
To confirm that you have read my blog, you need to turn in a half sheet "contract" or agreement to Paul stating that you have read my post and that you will step up to make exhibition the best that you can be. In your half sheet, please be specific as to what you plan to do to help out or where you think that you will be the most helpful.
In times of trouble, we should do the right thing. For me, it is honoring my grandmother and aunt by traveling across country. For you, it is stepping up to help your teachers, peers and school demonstrate what students are REALLY capable of at High Tech High. Feel free to leave a comment to this post so I know I have your support as well.
I am looking forward to seeing how everything comes together.
