GEOMETRY A ATTENTION MATH STUDENTS ! When: The first Tuesday class meets Tuesday August 21st at 12:30-2:30. Where: The Math Classes meet in room C-212. Be Ready for the First Day of Class: 1. Bring the “Summer Plan” work in a folder with the total number of correctly worked problems listed on the cover sheet. The “Summer Plan” is made of any math problems the student has worked during the months of June, July and August, using problems from the math course he has just finished). The purpose is REVIEW. If the student has done no math during the summer, he has probably forgotten some of his last year’s material. This review of his last year’s work is crucial, so that he will not begin the new course this fall with a knowledge deficit and be behind classmates! Place all checked and corrected math problems worked during June, July and August in a folder with the total number of problems worked written on a cover sheet. He will receive extra credit (Bonus Points) for this work in a ration of 1bonus point for every 4 problems correctly worked. 2. Geometry students, pre-read 1-1 through1-4 (pages 3-25) and be ready for a quiz over the Postulates 1-11 and definitions in sections 1-1, 1-2, 1-3, and 1-4. 3. Make, memorize, and bring flashcards to be checked. See attached vocabulary pages. 4. Have your questions about sections 1-1 through 1-4 ready. 5. Have your name on everything: spiral, binder, calculator, text book’s book cover, etc. Bring to the First Class: 1. Text book: Addison-Wesley’s Geometry ISBN 0-201-29022-7 or ISBN 0-201-81260-6 or other more recent editions. These books are available to rent for the year from TAFA for $20. Please pick up your book as soon as possible so that you can complete the Pre-first class assignment! 2. Flashcards (3x5 cards) made from the attachment “Pre-first Class Vocabulary”. Make flashcards for all terms you do not already know. Bring blank cards to make new flashcards in class every week. 3. Summer Plan work in a folder.(Any math problems worked as review during the summer.) 4. Spiral notebook for note taking. 5. A scientific calculator (costs less than $15). 6. Two binders: one for current work and one to store returned homework, quizzes, and tests. 7. Pen, pencils, paper, compass, protractor, graph paper, blank 3x5 cards, and hi-liter. 8. Worked “Practice Problems” (the “Examples” and “Try This” on pages 4, 8, 9, 14, 15, 21, and 22). *Students will receive two handouts that are to be signed by parents and checked at the 2nd class. Each Week: 1. Work the assigned problems over the lessons taught in class. After Mom or Dad grades the odd numbered problems (answers in back of book), the student corrects each missed problem on a Corrections Page stapled to the front of that lesson. All work must be shown. 2. Pre-read the next new lessons to be taught as assigned and come ready to ask questions about any new or old problems that are troublesome. 3. Student work the “Example” problems and the “Try This” as a mandatory part of the assignment, and writes the total number of these worked problems at the top of his page. These become Bonus Points. Bonus Points are added to ChapterTest grades! 4. Students keep all returned papers neatly organized in the storage binder. 5. Student write all assignments in the back of his Spiral notebook each week. 6. Students check the weekly email I send. 7. Students be ready for a Quiz over homework (information taught in the previous week’s class). * Students get “overs” on the Problem Sets and the Practice Problems, meaning their grade reflects the total number of correctly worked problems after all possible corrections are made. ** SHOW ALL WORK . Work problems as shown in class . No work shown means no credit. *** Parents, please sign all work turned in by your student: homework problem sets, practice problems, tests taken and supervised at home, etc. Dress Code: To provide the optimum, distraction-free learning environment and as an expression of our conservative, Christian values, I respectfully request that you honor the TAFA dress code. “Work hard at whatever you do.” Ecclesiastes 9:10 Diligence leads to success. Proverbs 10:4 “You are young, . . . Be an example to show believers how they should live. Show them with your words, with the way you live, with your love, with your faith, and with your pure life.” 1Timothy 4:12 Mary Hamilton Thanks for your careful attention to this important information.

In fact, by attending early in the semester, a parent will better understand the class format and better able to encourage the student! Please print and file the above and below information and file all hand-outs in your binder for future reference. Please email me (“REPLY Geometry A”) back so I’ll know that you accessed this syllabus and so that I’ll have an accurate email address for you .
