Welcome to Everybody Likes Math 7!  Below, you will find some helpful guidelines to ensure success this school year!

Class Materials

Always have the following materials with you in class:

-pencils-all math work should be done in pencil

-notebook paper

-agenda

-math binders (2 inch 3 ring binder) with dividers

-scientific calculator

Binders

            You are required to keep a binder for this class.  The dividers in your binder should be labeled as warm-ups, classwork, homework and vocabulary.  In the homework section all assignments will be recorded on a Homework Recorder.  Those assignments will remain in the binder in the same order as on the Homework Recorder.  A binder check will be given periodically and will count as a quiz grade.

Grades

            Your grade in this class will be determined in the following manner:

                                                -Tests/Projects         30%

                                                -Homework               10%

                                                -Classwork                35%

                                                -Quizzes                    25%

Warm-ups

            When you enter class a warm-up problem will be displayed on the overhead projector.  Warm-ups will be collected every week (on Fridays) and will be recorded as a classwork grade.  Each day is worth 10 points.  Warm-ups should be completed on the warm-up sheet provided and kept in the binder until the due date.

Weekly CRCT practice

            Weekly CRCT practice

            Students will be responsible to do at least 16 weeks of CRCT Practice that is found in their textbook.  Each 2 weeks the students will receive a CRCT practice worksheet that they will have to fill out.  They need to identify the week number and the day.  Under each day the students should Show their work and give an explanation of their solutions.   All solutions need to be written on the answer line.  These CRCT Practice problems can be found in their textbook on pages GA 4 – GA 27.   This will count as a class work grade.  The following is the rubric on how this work will be graded:

                                    Following all directions                 50 pts

                                    Completed at least 16 wks 30 pts

                                    Accuracy                                           20 pts

Homework

            Homework is assigned almost every night. It will be checked or graded and should be completed to ensure proper retention of concepts learned in class.  I will accept late homework assignments only within the week it was given.  Every day it is late the grade will drop.  For example, if you forgot to show me your homework on Monday or Thursday you have until that Friday to show me your homework for some credit.  Projects and quiz corrections will not be accepted late.

Makeup Work

            

Cobb

County

policy allows a student 1 day per day absent to make up work. 

Textbooks

            Students are assigned a textbook and are responsible for replacement costs of $51.00 if the book is lost.  The textbook is assessable online with a username and password.  Usernames and passwords will be given out in the next few weeks.  If you do not have access to the internet you can receive a copy of the textbook on CD.  All you have to do is bring in a writable CD to your teacher.

Daily Procedures

            Enter class promptly

            Copy EQ? and homework assignment in agenda

            Start warm-up

            Check homework/review

            Mini Lesson

            Activity/practice

            Summary

Class Rules

Be on time.

Be prepared.

Be on task.

Be RESPECTFUL.

Speak only at appropriate times.

Other Expectations

            All math work will be done in pencil.

            Chewing gum, food, and drinks will not be allowed.  (Water will be allowed.)

            Work must be shown to receive full credit on work.

            Binder organization must be maintained daily.

            Do not get out of your seat without permission.

            Do not expect extra credit will be given.

            It is the responsibility of the student to obtain make-up work.

Math 7 Unit 1 Dealing with Data

Dear Parents,

Welcome to the 2007-2008 school year! We are eager to work with you and your student as we learn new mathematical concepts. The State of Georgia is introducing Performance Standards that call for students to be actively engaged in doing math in order to learn math. In the classroom, students will frequently work on tasks and activities to discover and apply mathematical thinking. Students will be expected to explain or justify their answers and to write clearly and properly.

Mathematical content will be organized in units based on the content of the Georgia Performance Standards (GPS). Since most textbooks published before the adoption of the new standards do not contain all the topics addressed in the new GPS, the teacher will be providing content notes in class and supplementing practice through tasks. When appropriate, problems will be assigned from the text.

Unit 1

Enduring Understandings

·          Data can be represented graphically in a variety of ways. The type of graph is selected to best represent a particular data set.

·          Measures of center (mean, median, mode) and measures of variation (range, quartiles, interquartile range) can be used to analyze

      data.

·          We can use graphs to investigate the relationship between data sets.

Unit Essential Question:

How do I choose and create appropriate graphs to represent data?

Key Standards:

·          M7D1. Students will pose questions, collect data, represent and analyze the data, and interpret results.

·          M7A3. Students will understand relationships between two variables.

Vocabulary:

  • box-and-whisker plot

  • lower quartile
  • upper quartile

  • interquartile range
