We continued our work with compound inequalities today by taking a look at how to work with disjunctions.  Between conjunctions and disjunctions, the graphs of compound inequalities now have a complete picture.  We went through 5-6 examples together before the students got started on their homework towards the end of the period.

We will cover one more section tomorrow before then taking a quiz over sections 9-1 to 9-3 on Friday.

Indirect Proof worksheet

1.  triangle ABC is scalene;  or triangle ABC is not equilateral
2.  a < b
3.  angle X < angle Y
4.  Doug is not a Canadien
5.  Kim is a violinist
6.  CX is a median of triangle ABC
7.  don't do
8.  Assume a is parallel to b
     Reason:       angle 2 is congruent to angle 3    (vertical angles congruent)
                         angle 1 is congruent to angle 3    (corresponding angles congruent)
                         angle 1 is congruent to angle 2    (transitive / substitution)
     m angle 1 = m angle 2 contradicts the given that m angle 1 does not equal m angle 2
    Assumption is wrong, therefore a is not parallel to b

9.  Assume angle J and angle K are both right angles
     Reason:      OE is congruent to OE   (reflexive)
                        triangle JOE is congruent to triangle KOE   (AAS)
                        OJ is congruent to OK    (CPCTC)
     this statement contradicts the given that OJ is not congruent to OK
     Assumption is wrong, therefore angle J and angle K are not both right angles

10.  Assume OE does bisect angle JOK
       Reason:    angle 1 is congruent to angle 2   (def. of bisect)
                        OE is congruent to OE    (reflexive)
                        triangle JOE is congruent to triangle KOE   (SAS)
                        JE is congruent to KE   (CPCTC)
      This statement contradicts that JE is not congruent to KE
      So the assumption is wrong, therefore OE does not bisect angle JOK

Course Description:

Algebra 10-12 is year-long entry-level math course that students can receive high school credit for.  The prerequisite for this course is that a student has already made an unsuccessful attempt to pass algebra 1.  The class covers Algebra standards set by the state and district.  At the end of the course, the students will be able to take an end of course (EOC) Algebra exam that can fulfill a graduation requirement for the Richland School District.

Course Overview:

ü  Introduction to Algebra / Review

ü  Integers and Rational Numbers

ü  Equations

ü  Inequalities

ü  Exponents and Polynomials

ü  Polynomials and Factoring

ü  Graphs and Linear Equations

ü  Systems of Equations

ü  Inequalities and Absolute Value

ü  Rational Expressions and Equations

ü  Radical Expressions and Equations

ü  Relations and Functions

ü  Quadratic Equations

ü  End of Course Review

Course Goals and Mastery Levels:

ü  Students will achieve mastery (80%) of the above concepts and pass the class.

ü  Students will achieve a passing score on the EOC exam.

ü  Students will be prepared to successfully go on into Geometry

Course Materials  (to bring to class every day)

ü  A notebook and paper, including graph paper  (3-ring binder with sectional dividers)

ü  Ruler, pencils, and erasers; 

ü  If tests and quizzes are done in pen, however, there will be a 5% deduction.

In-Class Expectations

ü  Eating and drinking is not allowed in class, unless the liquid is water.  I do allow gum in class, provided it is not seen or heard.

ü  Electronic device policy:  If I see it or hear it, I collect it and you get it back at the end of class. 

ü  Phones are not to be used as calculators in this class.  If you need a calculator, you can borrow one.

ü  All tardies are recorded and handled by the office.  Be in your seat when the bell rings.

ü  Keep the language positive in your conversations with and about others.  No swearing please.

ü  The desks are clean.  Please keep them that way by not writing on them. 

ü  Respect others by listening well and responding appropriately when they are done speaking.

ü  During partner work time, work and share the responsibility with who you are working.

ü  If you’ve got a question or comment, please raise your hand and wait to be acknowledged.

ü  Use your class time well.  Use the class-time that I give you to get started on your homework.

Be ready to work every day!  Math is a doing sport!  It is not a spectator sport!

Grade Calculation:

Tests: Tests are worth 50% of the grade.  There will be a test given at the end of each chapter and at the end of each semester.  The semester test will be worth the equivalent of two regular test scores.  Any student absent from class is expected to make-up the test upon returning.  It is the responsibility of the student to arrange a make-up time with the teacher. 

Quizzes:  Quizzes are worth 20% of the grade.  Quizzes will be given on a regular basis throughout each chapter.  Any student absent on the day of the quiz is expected to make-up the quiz upon returning.  It is the student’s responsibility to arrange a make-up time with the teacher.            

Homework: Homework is worth 30% of the grade.  You will grade your own paper in class before turning it in.  Papers turned in with no name will receive no credit for that day’s homework. 

Late Policy:  Homework assignments turned in late will receive a 50% deduction.  Assignments turned in over a week late will not be accepted.  Late is after we collect the assignment at the beginning of class.

Grading Scale

93-100  à  A              83-86   à  B               73-76   à  C                           60-66  à  D

90-92    à  A-             80-82   à  B-              70-72   à  C-                            0-59  à  F

87-89    à  B+            77-79   à  C+             67-69   à  D+                        

Retesting Policy

A student can ask to retake one test per semester if they so desire.  The highest score that can be earned on a retest is 85%, and the grade on the retest is the one that will be recorded.  It is the student’s responsibility to ask for and arrange a time to retake the test with the teacher. 

Absences

è If you are absent, you have that number of days plus one to make up your work.  If you are gone 1 day, you have 2 days to get the make-up work turned in.  If you are absent 5 days, you will have 6 days to get the make-up work turned in.

è Students are required to get work ahead of time for planned absences.  This includes all school activities and sports.  Failure to comply will result in a late assignment.

è If there are extenuating circumstances, please communicate these with me as they come up.

Online Communication

I post a blog on a regular basis of the ongoing assignments for this class.  It is listed under the geometry heading on the blog.  This information is also communicated in the classroom.

Regular (almost daily) homework is a part of this class, so keeping up with the assignments and knowing the schedule is a key part of success in Algebra 10-12.   

Be ready to work every day!  Math is a doing sport!  It is not a spectator sport!
