TYPICAL CLASS PERIOD: The first part, twenty to fifty minutes, of class is open for answering questions about the previous assignment including exercises, reading material, or classroom notes. You are encouraged to answer other students assignment exercise questions by presenting chalk board work. While presenting exercises is expected, this communication is not graded. Use this time to experiment with your ability to understand an exercise and convey your understanding to others. Don't worry about any mistakes you may make, that's part of learning.

The second part of class is used to introduce new material with examples and discussion. It is generally assumed that prior to the date listed on the Course Schedule, you took notes as you read from the new section(s). You may wish to include the textbook examples in your class discussion of new material and your instructor will cover some of these and other examples. Individual communication is not permitted in class while attention is directed to one individual. Some class time may be devoted to group problem solving. You are encouraged to get phone numbers from other students in class and talk about problems in the homework assignment.

HOMEWORK: For each section listed below, read the topics discussed in class and work every other odd numbered exercise (1,5,9,...). Develop your problem solving methods on the first few exercises of a given type then work for speed and accuracy. Complete other odd numbered exercises if needed for mastery. Ask about the stubborn unfinished exercises at the start of the next class meeting! Develop a dogged attitude about doing homework problems on time and frequently review. Each exercise section will take several hours or more. Spread weekly homework evenly over four to six days for best results.

A few students enjoy working extra problems that relate to the course material. Some problems and projects will be posted here and feel free to suggest additional ideas when you meet with your instructor. Algebra Properties for geometry moves is your first suggested project. ( 10 points )

Ask for help if you need to develop better test taking skills. The final exam will count as two units.

GRADES AND THE GRADE SCALE: Test grades correspond to percentages of highest raw scores. The final grade is based on the average of test units with the following scale used on each unit.
A 90% - and above,
B 80% to 89%,
C 70% to 79%,
D 50% to 69%, and
F below 50%

Attendance: You are expected to attend all classes. Call me before class if emergency conditions prevent you from attending.
