Portfolio Details

In lieu of the newspaper articles, you should include 2 word problems for each chapter (2-8). The problems should test different concepts.

Fractions Graph Paper Workbook

An interesting article in the Proceedings of the National Academy of Sciences entitled "Female teachers' math anxiety affects girls' math achievement". A more accessible summary can be found here.

Exam 1 Review Problems and (mostly) complete solutions

Exam 2 Review Problems and complete solutions. Errata below. If the errata below all looks like gibberish, please e-mail me and let me know!

- I said this in the solutions, but I want to make it totally clear: Don't think about problem 21 as a fraction division problem. You don't know fraction division yet. Try to figure out how to do the problem by drawing diagrams and using what you know about fractions!
- In 1c, the solution should be:

[; \left(2^3\right)^5 = 2^{3\cdot 5} = 2^{15} ;]

rather than a blank space followed by an incorrect answer. I got distracted mid-correction on that one. - The
**problem**in 7a is incorrect. It should be base 9, not base 7. - 7b has an addition error. The answer should be 16004
_{(8)}. - In 11a, I forgot to include the solution to the LCM.

[; \textrm{LCM}(3073,2359) = \frac{3073\cdot 2359}{\textrm{GCF}(3073,2359)} = 1035601 ;] - In 11b, there's a sentence that reads "... since ____ is their greatest common factor." The big blank, obviously, should be a 7.

Final Review Problems and complete solutions

- In problem 19, everything should be base 4.
- On problem 29 I forgot to mention that 6 of Albert's friends are not horrible people.
- On the solutions to problem 4a I did 4/3-5/3 instead of the correct problem.
- In the solution to 8a, everywhere you see "51" pretend it says "26".
- In 19c there should be two dots in the rightmost column of the first three diagrams rather than one. They mysteriously reappear in the fourth diagram.
- The answer to problem 16 is 15717, not 14717.

Worksheet At some point you should re-create the table and Venn diagram on this worksheet, adding integers, rational numbers, real numbers, and irrational numbers. |

All homework problems are from the book, unless otherwise specified. I recommend you spend as much time as necessary to get them right. Practice is the only way to learn math.

Also, be warned that though the assignments are given on Tuesdays, they will sometimes include material to be covered Thursday. Don't get discouraged if you can't finish the last few problems initially.

Some of these homework assignments are quite long. They are mainly meant to provide you with mechanical proficiency, so if you are short on time, focus on the exercises instead of the problems. You'll have time to do problems in class.

This is a **tentative** schedule of how the class will go for the rest of the semester. As it stands, it does not include the optional chapter 9 material, but it's probable that we will have a chance to spend at least a day on it. I will revise it as the semester goes on.

This form is intended to give you a chance to give me anonymous suggestions, comments, requests, or complaints about the class, without needing to come in and say them to my face, which I understand can be a bit terrifying at times.

If you have a complaint, please try to keep it specific and constructive. The less specific your complaint, the harder it will be for me to rectify it.
