Text: MN Go Math, Grade 7, 2018 edition, HMH
Length: 1 year
Grades: 7
———————————————————————————————————–
Class Expectations:
Let Mrs. Smith teach
Be Respectful
Come Prepared
Here are a few, not all, procedures that you will help you to meet the expectations listed above.
- Enter classroom calm and quiet.
- Use your passing time wisely to eliminate hall passes. Students must be in class when the bell rings. Leaving your books, does not mean you are excused to be late.
- Listen and pay attention when class starts.
- Raise your hand! Do not blurt out answers to questions.
- Wait to be dismissed at the end of the hour.
Seating Charts – we will have one .
A seating chart will be arranged. The arrangement can be changed at any time. Students are expected to sit in their assigned seats each day.Books – Please put a book cover on your book.
Our books must to be handled with care! A grocery bag and masking tape works well. Do not use glue or anything that will stick to the book. Book covers are to be put on at the beginning of the year and expected to stay on all year.
Tardies and absences
Arriving late to class will count as a tardy. See the student handbook for the school’s attendance policy and makeup work policy.
Grading – Grades will consist of warm-ups, notes, homework, quizzes, and chapter tests. Test will make up the majority of your grade.
Grades are earned based on the following percentages: 50% tests & quizzes, 25% homework, 25% notes & warm-ups Grading Scale: | ||||
93-100% A | 80-82% B- | 67-69% D+ | ||
90-92% A- | 77-79% C+ | 63-66% D | ||
87-89% B+ | 73-76% C | 60-62% D- | ||
83-86% B | 70-72% C- | < 60% F | ||
Warm up exercises: Warm-up exercises are to be completed when you arrive in class and should take 5-10 minutes. You should start working on these right away. We will go over these problems each day. Note: These exercises are worth 5 points per day. If you are tardy to class, you will not receive the daily points for the warm-up exercises.
Notes: I will grade your notes; they are worth 5 points for each lesson. Students should have a composition notebook reserved for math to take notes for the day. The date and topic should be used as the heading for the notes each day. Take notes in date order however, each day does not have to start on a new page. Bring this notebook to class everyday!
Assignments: Assignments will be given almost every day. Grade reports, will help you know what missing work you have. You can ask me to see yours, or get it printed, and any convenient time.
Assignments will either be corrected in class or collected and graded. Show your work! Math is about learning the process, you need to show that you can do the problem step-by-step. I do not give credit if you do not show work.
Late Work: Assignments are expected to be done when due. All late work is due within 7 days of the assignment due date for possible full credit on the assignment. Any work turned in after one week from the due date will receive one point. Any missing work will be marked as a zero in the gradebook until the work is turned in and graded. Any work that is not turned in will remain a zero.
Work due to excused absences will be accepted according to the student handbook. (Due immediately upon your return.) See the Student Handbook for more specific information.
Tests: Tests will be given at the end of each chapter. Each test is weighted equally, worth the same number of points. Study and be prepared for them. Students will not be able to take the chapter test if they have not done the assignments…this means you cannot take the test if you have missing work. The student will be responsible for scheduling a time, within one week of the class test date, to take the test at a later time. Missing work must be completed. Retests will be offered, however always strive to do your best the first time! No retest on take-home tests. You will need to complete “corrective” problems before retaking a test. These “corrective” problems must be done well before you can take the retest. The correctives and retest will be due one week after I return the original test and must be done outside of class time.Quizzes: There will be various short quizzes, scheduled and unscheduled, throughout the year. Generally, quizzes are worth 10 to 20 points. There are no retakes on quizzes.
Extra Credit: There may be various impromptu extra credit options offered throughout the quarter. Extra credit is truly “extra” work, it will not be accepted from students who have missing regular work. Extra credit options will be given a due date and will not be available at the end of a grading period.
Math Hints:
- Use a pencil! Work in pen will be returned.
- Show your work! Math is about learning the process; you need to show that you can do the problem step-by-step. No work = no credit.
- It is important to keep your math work neat, others need to read it.
- Students need to put their name and the assignment (page number and problems) in the upper right-hand corner of their papers.
Preparing for class – bring your materials each day!
Materials to bring to class each day:- Completed homework…Practice makes perfect!.
- Textbook.
- Pencil/eraser…or two that is ready to use…sharpened or have lead.
- Red pen for correcting.
- Paper
Be ready for class. Have multiple pencils ready, get a drink of water, use the restroom, throw away paper, etc. BEFORE class begins. Any garbage that needs to be thrown away or recycled, hole punching, stapling, etc. can be done after class. If you have to borrow supplies, do so BEFORE class begins. Be ready!
