# Homework For Math 1b, Fall 2005

Because this class meets both MWF and TTH, we have two schedules of homework. So we list the problem sets, then the schedules of which are due when, depending on section scheudule.

## Numbered Problem Sets

These problem sets are taken from the course textbook. Note that that we are using the 3rd edition of the textbook, not the 2nd, and the problems are different between editions. It is your responsibility to make sure you are doing the right problems!

In order to be fair to fellow students and to the course assistants grading the assignments, problem sets must be turned in on time. We understand that situations arise when homework loses priority, and so when computing your final homework grade, your lowest three problem set scores will be dropped.

One of the goals of this course is for you to learn how to think and communicate mathematically. This means that your homework problems should be written up with justification and explanations of your steps in English. See the textbook examples for examples of how to write up a problem well.

Some exam problems will also ask for justifications, so this will be good practice.

Each problem will usually be worth 3 points. Multi-part problems will have each part graded on the same scale. We are grading each three-point part according to the following rubric:

Points Description of Work
3 Work is completely accurate and essentially perfect. Work is thoroughly developed, neat, and easy to read. Complete sentences are used.
2 Work is good, but incompletely developed, hard to read, unexplained, or jumbled. Answers which are not explained, even if correct, will generally receive 2 points. Work contains “right idea” but is flawed.
1 Work is sketchy. There is some correct work, but most of work is incorrect.
0 Work minimal or non-existent. Solution is completely incorrect.

Each of these is detailed in the "Q&A Tool 2.0" Section of the course web site. You will be normally asked to read part of the book (part of a section, a section, or more than one section), then answer questions through the Q&A tool. Click on an individual assignment for more information.

Quoting from the syllabus, "There will usually be two questions for each reading. One will be asking what you found most difficult in the reading. The other will be specific to the reading topic. Both will be graded mostly on effort.

"The purpose of these assignments is twofold: You will get an extra pass through the material so that by the time you sit down to do the homework you have seen it at least twice. Also, your section leader will read your responses before class and use it to prepare the section with your confusions in mind."
