**TEXTS:**
*Mathematics for Elementary Teachers* (3rd edition) and
*Activities Manual*,
by Sybilla Beckmann (These are packaged together. The ISBN for the
package is: 0321654277).

**Course Description and Expectations:**
This is the first course in the three-course sequence of Math 105, 106
and 107. Math 105 focuses on concepts of number systems and operations.
The goal of this course is to prepare you to become teachers of
elementary and middle school students. Knowing the mathematics for
yourself is not the same as knowing the math for teaching. To that end,
we emphasize explanations of mathematical ideas. To make this point very
clear: Full credit will NOT be given for correct mathematical answers
without an explanation that is clear and complete.

*Attendance and participation* is critical to your success
in this class. Each class will consist of doing an activity in a small
group and discussing it with the whole class. You are expected to
participate actively in all phases, so please bring the Activities
Manual to each lecture and recitation. Explaining your thinking verbally
in small and large groups will prepare you to explain mathematics with
your students. It will also help you clarify your own ideas and/or
questions.

*Reading* is crucial because we do not teach using the traditional
lecture format. Reading assignments are designed to provide the explanation
and summary of material that are not provided in class. You are expected to
complete all reading assignments. You will find the Practice Problems
and their solutions particularly helpful.

**Overall Grading Scheme:**

Attendance & Participation 10%

Homework: 17.5%

Quizzes: 17.5%

Midterm exam: 25%

Final exam: 30%

Final quarter grades will be determined according to the scheme.

A | A- | B+ | B | B- | C+ | C | C- | D+ | D |

90 | 87 | 83 | 80 | 77 | 73 | 70 | 67 | 63 | 60 |

**Exams and quizzes:**
There will be one midterm and one final exams.
Most Wednesdays there will be a 15-minute quiz (10 points) on material
taken from the homework and activities completed in lecture and
recitation since the previous quiz. Activities listed on the syllabus
but not completed in class should be finished outside of class on
quizzes, you will be responsible for all the material in the assigned
activity.

**TENTATIVE EXAMINATION SCHEDULE:**

MIDTERM | Wednesday, October 27. | FINAL EXAM | Monday, December 6, 6:00-7:48 pm |

**Homework:**

There will be weekly homework assignments. Homework assignments will
receive a score out of 15 points: you will receive 5 points for
completing all of the problems (less if you do not) and ONE randomly
selected problem will be graded on the 10-point scale.
The graded problem will be assessed on both the quality of
your explanation and the correctness of your solution.
