#### Possibilities for dropping a homework grade

You can earn the right to drop up to two, but no more, of your
homework grades. If you do so, then at the end of the course,
your lowest one or two homework grades will be replaced by a perfect 10.
The possibilities for earning this are as follows:
- Attend a math seminar.
You should e-mail us to let us know when you go. We will then ask you
to say a word about it in class the next day. You can earn this
credit by attending any math seminar. See the department's Weekly Calendar
for the complete listings.
owever, two particularly appropriate seminars are:
Geometric Potpourri, Tuesdays at 2:00 p.m. in 243 Altgeld Hall, and
Mathematics in Science and Society, some Tuesdays at 4:00 pm in
Altgeld 245. Links to the schedules for these are available on
the course webpage web page. Note that you should not expect to
understand everything in the talk you go to--nobody does--but you
should at least try to understand the main idea of the talk.

- Crochet or knit a hyperbolic plane. Instructions can be found
in your textbook. If you choose this option, you will be asked
to bring in your hyperbolic plane to class from time to time.
However, you should find that having your own model makes it
much easier to answer some of the problems we will ask in this course.
Again, you need to e-mail us to get a permenant record so that
you will get credit. (There are probably other construction methods
that, unlike paper, will result in sturdy and permanent models; if
you have another idea for constructing a sturdy model, please talk
to us about it.)

- Write a lesson plan for any of the material that you have
learned during this course. This should include
- The grade and level of the students.
(The grade can be anywhere from preschool to 12th grade,
and the level can be anywhere from special education to a project
for just the few most gifted students.) You should
also mention prerequisites, if there are any.
(You are welcome to plan
a lesson that fits into the middle of a course, but make this clear.)
- Materials needed, if any.
- The objective of the lesson, that is, what you hope the
students will be able to accomplish by the end of the lesson.
- The plan for what you will actually do in the lesson.
This should include estimated time, the method(s) of instruction
that you will use, and what techniques you would use
to analyze the students' understanding.

A reasonable length should be a page or two. You should then
make 60 copies of your lesson plan so that we can distribute them
to all the students in Math 302.

Note: please don't wait until the last minute to do these.
In particular, the crocheting needs to be done in the near future,
so that the model can be used during the course. Similarly,
the others should be done before the end of the semester
so that we will have an opportunity to discuss them in class.
