                         Class Procedures
• Assigned Seats-You will be assigned seats and are expected to sit in your
  assigned seat every day. These seats will change throughout the year.
• Attention – If I would like your attention, I will count down from three, two , one
  or sometimes hold up my hand in an “O” shape, and ask for “level zero.” This
  means that you should end all conversation or noise and face forward.
• Late arrival to class – There are five minutes between classes, this is including
  how you will arrive to class by lining up in front of the classroom and taking your
  math notebook out. The line should be two straight lines one boys and one girls
  line. If you are not in your seat by the time I allow the class to enter or the bell
  rings, you are cutting. If you are in the room, but not in your seat, you will be
  marked cutting.
       •Unexcused lateness -If you are late to class for an unexcused reason, and
       we have already handed in a Do Now, or completed a quiz, you will not
       be permitted to retake the Quiz or Do Now. This will get marked in the
       grade book as a 0.
• Absence from class – If you have been absent from class, please call your work
   buddy to find out what you missed. Also, note you ARE RESPONSIBLE for the
   content discussed during the class, as well as for the homework assigned. “I wasn’t
   there the day we did this in class” is NOT an appropriate excuse. If you do not feel
   comfortable learning the material on your own, attend tutoring – or better yet, try not
   to be absent. It is your responsibility to schedule a time with me to make up the
   missed work. If you do not, your grade will remain a 0. If your absence is
   unexcused (e.g. cutting class), you will not be permitted to make up work. Your
   grade will remain a 0.
• Absence on test day – You are allowed one test absence per semester. Absence
  during a test should be a rare circumstance. If you are absent on a test day, that
  grade will be dropped for you. This is to ensure timely return of exams to students.
  After one test absence, you MUST provide a doctor’s note, and schedule a make-
  up exam.
• Absence notes – Only notes from a medical doctor (or parent for homework) are
  acceptable as absence notes.
• Late notes – Only notes written and signed by another teacher are acceptable as
  late notes. If the class is your first class of the day, you must provide a note from
  your parent as a late note.
• Entering the room at the beginning of the period – At the beginning of the
  period every one is to line up outside quietly in the hallway with their math
  notebooks out. When you enter the room, you should quietly go directly to your
  seat, sit down, and begin working on the Do Now problem. all HATS, MP3/music
  players, cell phones, etc, should be OFF AND AWAY BEFORE walking into
  class. If you need to obtain a pencil, sharpen your pencil, obtain paper, etc, you
  should arrive to class with sufficient time prior to the bell to allow you to do these
  or other activities.
•
• Leaving the room at the end of the period – You are only to leave your seat when
  given permission, and this includes at the end of the period. The class will either be
  dismissed via individuals, desks, rows, or as a class. You are to remain in your seat
  until you are dismissed. Please do not start packing up until you are given
  permission to leave. Once you are dismissed, you may collect your things, and
  promptly leave the room. Do not engage in any activity (roughhousing, horseplay,
  foul language, etc) that you would not otherwise engage in during class time. You
  are still in class.
• Going to the restroom – The time between classes is to be used for bathroom
  needs. If you must go to the restroom during class, please raise your hand. If given
  permission, quietly get up without distracting the class, take the pass, use the
  restroom, enter class, quietly return to your seat. If you show that you can not
  properly follow this procedure you may lose the right to go the right to go to the
  bathroom. In addition, if you are late to class, you may also lose the right to go to
  the bathroom.
• Going to the nurse – If you have to see the nurse, please raise your hand and ask. I
  will walk over and have a brief discussion with you regarding the illness. If a
  nurse’s visit is appropriate, I will write you a note. If you go to the nurse’s office
  and she is not present, follow the procedures for returning from the bathroom when
  returning to class. If you would like to try the nurse again at a later time, raise your
  hand and hold up the note.
• Going to the library – The only library time that is permitted is when we go to the
  library as a class for research purposes. It is not appropriate to miss class in order to
  work in the library on projects for this, or another class.
• Loudspeaker Announcements- If an announcement is made over the loudspeaker,
  please finish conversations so that all students can hear the announcement. I will
  ask for, and expect, level 0 noise.
• Pulled out of Class-If I am pulled out of class for an unexplained reason, please
   continue to work on your assignment
• Fire Drills – Fire drills are usually scheduled during first and last few months of
  school. An announcement will come over the loudspeaker, and the drill typically
  occurs 2-3 minutes after the announcement. After the bell for the drill rings, wait
  for my permission to get out of your seats. Then stand up, and line up quietly at the
  door. I will ask the first person to lead us down the stairs. At no time between
  lining up for the door, and leaving the building, should students be talking.
• Sharpening Pencils – Pencils should be sharpened prior to the start of class. Please
  bring a backup pen or pencil so that we can minimize time used for sharpening
  pencils. If both pencils break, raise your hand and hold up both pencils. I will walk
  over and give you a hand sharpener. Please leave it on your desk when you are
  done, and I will collect it at a later point in time.
• Getting materials – Handouts will be distributed by the appropriate selected
    students. So that we can minimize the time it takes to hand out materials, do not
    engage in conversation with the materials person.
•   Class materials – You are expected to have two pens/pencils, a composition
    notebook and a calculator. I will not distribute class materials, except for scrap paper
    during an exam (when you are not allowed to have any materials other than a
    pen/pencil). Please do not ask me for a pen/pencil/paper/calculator as I will NOT
    give these materials out. If you fail to bring the appropriate materials, or are not
    able to borrow them from another student BEFORE the bell rings, you will not be
    able to complete any of the required work for the class.
•   Homework Collection – Homework is assigned every night, collected every day,
    graded, and returned typically the next class day. Therefore, there will be
    homework to be collected on an almost daily basis. When you arrive in class and
    are seated, leave your homework on the top of the desk. Homework will be
    collected by the class work collector. Again, so that we can minimize the time it
    takes to collect materials, do not engage in conversation with the collector.
•   Returning Homework – Homework will be returned by the appropriate selected
    student, and will follow procedures for getting materials.
•   Class heading – Notebook – the heading for each day in your notebook should
    contain the date, Aim, Do now, lesson notes and HW assignment
• Trash –1. Leave it on your desk until the end of the class. When you are dismissed
  from class, place, not throw, the trash into the trash can. 2. Raise your hand and
  quietly hold up the trash you would like to throw out. I will either walk over with
  the trash can or take from you and throw it out myself.
• Cell Phones – It is a city rule that you are not permitted to have a cell phone. I am
  not going to search every student when they enter class. I will take your cell phone
  if I hear it or see it. Cell phones may NOT be used as calculators, and therefore there
  is no need to have them on during class.
• MP3 Players – It is a city rule not to have MP3 players. You are not allowed to
  listen to your MP3 player/radio/CD player during class. This is not open for
  discussion. This applies at all times, whether during a test or while working on an
  activity. I realize that some students are less distracted when listening to it, but this
  is a school rule and it is enforced in this class. Please do not ask me if you can listen
  to it, and please do not tell me that other teachers let you. I only care about what
  goes on in this class, and in this class, it is not allowed.
• Getting the teacher’s attention If you have a question, or would like to speak or
  answer a question during discussion, please raise your hand and say, Ms. Raffi, so
  that if my back is turned to you, I can hear you. This includes answering any
   questions that I ask of the class.
Problem Solving is easy if you
      follow these steps

  Understand
     the
   problem
Step 1 – Understand the problem
• Read the problem carefully.
• Find the important information.
• Write down the numbers.
• Identify what the problem wants
  you to solve.
• Ask if your answer is going to be a
  larger or smaller number compared
  to what you already know.
Step 1 - Understand the Problem
  Read the problem carefully.
• Luis earned 14 Accelerated
 Reading points the first week of
 November. At the end of the
 following week he had a total of
 31 points. How many points
 did he earn the second week?
Step 1 - Understand the Problem
Find the important information.
• Luis earned 14 Accelerated
 Reading points the first week of
 November. At the end of the
 following week he had a total of
 31 points. How many points
 did he earn the second week?
 Step 1 - Understand the Problem
     Write down the numbers.
• Luis earned 14 Accelerated
  Reading points the first week of
  November. At the end of the
  following week he had a total of
  31 points. How many points
  did he earn the second week?
 Total = 31     1st week =14
 Step 1 - Understand the Problem
 Identify what the problem wants
           you to solve.
• Luis earned 14 Accelerated
  Reading points the first week of
  November. At the end of the
  following week he had a total of
  31 points. How many points
  did he earn the second week?
 Total = 31   1st week =14
        2nd week = ?
  Step 1 - Understand the Problem
Ask if your answer is going to be a
larger or smaller number compared
     to what you already know.
 Total = 31    1st week =14
         2nd week = ?
It will be smaller than the total but
may or may not be smaller than the
first week.
 Step 2 - Decide how you’re going
        to solve the problem
          Choose a method
Use a graph         Use formulas
Write an equation   Make a list
Find a pattern      Work backwards
Use reasoning       Draw a picture
Make a table        Act it out
Step 2 - Decide how you’re going
       to solve the problem
       Write your equation

 Total = 31      1st week =14
          2nd week = ?
Since I know both weeks total 31 I
               write
           14 + s = 31
  Step 2 - Decide how you’re going
         to solve the problem
         Write your equation

   Total = 31      1st week =14
            2nd week = ?
I can use the inverse operation to solve
                   for s
      14 + s = 31      31 – 14 = s
Step 3 - Solve the problem

Total = 31      1st week =14
         2nd week = ?
            2
          3 11
         –14
          17
   Step 4 - Look Back & Check
       Reread the problem
• Luis earned 14 Accelerated
  Reading points the first week of
  November. At the end of the
  following week he had a total of
  31 points. How many points
  did he earn the second week?
 Total = 31     1st week =14
   Step 4 - Look Back & Check
   Substitute your new number
• Luis earned 14 Accelerated

       2nd week = 17
   Step 4 - Look Back & Check
   Substitute your new number
• Luis earned 14 Accelerated
  Reading points the first week of
  November. At the end of the
  following week he had a total of
  31 points. How many points
  did he earn the second week?
       14 + 17 = 31
   Step 4 - Look Back & Check
   Did your new number work?
• Luis earned 14 Accelerated
  Reading points the first week of
  November. At the end of the
  following week he had a total of
  31 points. How many points
  did he earn the second week?
    14 + 17 = 31 Yes!
