BRIEF COURSE DESCRIPTION This course is an
intensive exploration of mathematical concepts and content
commonly taught in grades K8: problemsolving strategies; sets; functions;
logic (quantifiers, conditional and
biconditional statements); numeration systems; addition, subtraction,
multiplication, and division of whole numbers;
integers; greatest common divisor and least common multiple; addition,
subtraction, multiplication, and division of
rational numbers; integer and exponents ; decimals and operations on decimals;
percents; and algebraic thinking. See
chapter highlights for more information …
In this course we will focus on the math concepts and
content for grades K8:
• reconceptualize mathematics you think you already know
• learn mathematics at a much deeper level
• experience various types of reasoning
• learn problem solving strategies
• make connections among mathematical topics
• enjoy and appreciate mathematics
LECTURE NOTES Lecture notes will be posted the evening before class. Please bring your copy of the notes to class.
CLASS ACTIVITIES Some class meetings includes
structured cooperative learning activities to reinforce
fundamental mathematical concepts, to learn from others, to increase willingness
to try new problems, and to improve
frequency of success in problem solving. Cooperative learning activities
represent opportunities to meet other students
in the class to form study groups to work on the homework and prepare for the
exams . Cooperative learning activities
also help the class to maintain a positive classroom environment. The problems
contained in the activities summarize
the key concepts for the material covered. The problems we solve together meet
educational goals determined by
standards established by the National Council of Teachers of Mathematics (NCTM).
HOMEWORK ASSIGNMENTS
• Grading selected problems. Only selected problems in the
assigned homework will be graded, but all the assigned
problems must be worked for credit and to prepare for the exams. Each homework
assignment is worth 20 points,
with 10 points maximum for “effort” reflected in the submitted homework and 10
points maximum for
“correctness” of the graded problems. Sloppy, careless, slipshod, disheveled,
dowdy, shabby, unconcerned, frowzy,
or neglectful handwriting and improper use of mathematical notation typically
results in less points for “effort,”
therefore homework assignments should be written carefully and concisely.
• Incomplete homework. 1 point will be deducted for each
assigned problem that is skipped, ignored, overlooked,
omitted, disregarded, or forgotten, which can lead to low scores .
• Show your work (SYW). You must show your work (SYW) to
homework questions for credit. Partial credit will be
given as generously as appropriate.
• Link between homework assignments and your course grade.
There is a remarkable, noticeable, prominent,
outstanding, conspicuous, striking correlation between your grade on the
homework assignments and your course
grade, so please give the homework assignments the attention they deserve.
• Help! Many of the problems we solve in class will
resemble the homework problems you have been assigned. You
can work with other students, you can use my office hours, or you can see me
after class for additional help . You
can also receive free walkin tutoring from the CSUSM Math Lab, located in 1104
Kellog Library.
• Homework assignments and the writing requirement. The
2500 word writing requirement will be exceeded by
these homework assignments.
• Solutions. Detailed answers to the assignments will be made available after the due date.
• Late Homework. Late homework will not be accepted,
without exception (e.g., car trouble, illness, emergency, …).
But your two lowest homework scores will be dropped. You can scan it and submit
by email as a single PDF file.
EXAMS The date of the exams will be announced one
week in advance. You should study each weekend to avoid
cramming, which often causes confusion, frustration, disorder, chaos, agitation,
disarray, jumble, tangles, disturbances,
and hullabaloo.
GRADING Assigned homework, two exams, and a final
exam will be used to determine the final course grade.
These components have different relative importance:
Exam 1  Exam 2  Homework  Final Exam 
100 pts  100 pts  100 pts (scaled)  100 pts 
25%  25%  15%  35% 
Letter grades are assigned according to the following rule: 10090 = A, 8980 = B, 79 – 65 = C, 64 – 50 = D, 49 – 0 = F
EXPECTATIONS In this course, you will be expected
to
• Communicate ideas orally and in writing.
• Represent mathematical concepts using words, diagrams, algebra, manipulatives,
and contextualized situations.
• Learn problem solving strategies.
• Independently solve problems.
LOOSE ENDS
• Students who miss class are still responsible for announcements or changes
regarding the course outline, homework
assignments, due dates, and exam dates.
• Check your email regularly for announcements regarding this class.
• If you need to leave early, please inform me before class.
• You will need a password (TBA) to access posted material.
• Do not “crosstalk” during the lecture—it’s rude, disruptive, and
disrespectful to everyone.
• Please put your electronic gadgets in “silent mode” or “manner mode” before
class begins.
• Late homework will not be accepted.
• Extracredit work will be given inclusively beyond the course requirements.
Stay tuned!
• Everyone shares the responsibility in making this class an enjoyable place to
learn useful mathematics, make
inevitable mistakes, and share constructive ideas. Please help me create such an
environment.

reasoning is introduced as a way to make conclusions or
generalizations. Patterns are described, extended, and generalized. Tables are
used to organize and see patterns. Algebra
is used to generalize some patterns. Polya’s four phases of problem solving
process are discussed, and problem solving
strategies are illustrated with a variety of word problems. The roles of
variables are discussed, along with the
correspondence between word phrases and algebraic expressions . Additive and
multiplicative reasoning are introduced.

Chapter 3 Multiplication and Division with Whole
Numbers Multiplication is defined as combining equalsized
groups, as recommended in the literature. The various models of multiplication
and division are discussed, along with
the types of word problems that have multiplicative structure. The Singaporean
math model is used to represent and
solve problems. Properties of multiplication, which promote algebraic
understanding and proficiency, are explored

distribution of prime numbers. Clock and
modular arithmetic are discussed. Models are used to help define addition and
subtraction with integers. Inductive
reasoning is used to extend many whole number properties. Patterns are used to
motivate the rule for signs with
integers.
Chapter 5 Fractions and Rational Numbers Models of
fractions, nomenclature, symbolic notation, and various
interpretations of fractions are discussed. Division models are used to show
that a fraction is a quotient. The
Singaporean math model is used to represent and solve problems. Inductive
reasoning is used to establish the concept of
equivalent fractions . Common fractions, rounding, estimation, benchmarks for
comparing fractions, cross product rule,
and the density property of fractions are also addressed. Whole number
