Welcome to 8th Grade Math

WEEK OF SEPTEMBER 23, 2019

Parents:  Please note- tests were sent home this week.  You should ask your child about his/her first Math test of the year.

September 24, 2019 – New Topic SCIENTIFIC NOTATION

Remember the following are “ongoing assignments”:

(Refer to the meaning of “ongoing assignments” in the previous posts.)

After completing these assignments and study guides, you should be prepared to be tested on the next topic – “Scientific Notation”. Formative assessments are small assessments to see how much of the material covered you have mastered and to address any weak areas up to this point. These will be given intermittently.  Summative assessment (test on the entire topic) will be given after topic is complete.  

Refer to the Youtube presentation given in class “Introduction to Scientific Notation”. Note well what has been highlighted from that presentation.

  • During class – initial presentation from Sourcebook pages 36 & 37
  • Do “Try These” – p.36-37           
  • Ongoing assignment –  

     1.Writing numbers in scientific notation, writing numbers in standard form from scientific notation- Complete p.39 & 40,  # 1-39 in Foundations Book

  1. Ordering in scientific notation – p.39 (Review), p.40 #40-55 in Foundations book
  2. Problem solving basics in scientific notation – p.40 # 56-57 solve and check to verify your answer

FORMATIVE ASSESSMENT????? 

  • STUDY  p 80 & 81 in Progress Book- Describe how to multiply numbers in scientific notation; complete p. 41 in Foundations Book; 
  • Progress Book: Guided Instruction p.82 & 83-describe how to divide in scientific notation
  • Do page 42 in Foundations

SOLVING WORD PROBLEMS USING SCIENTIFIC NOTATION

  • The following word problems should be completed and answered as directed: Foundations Book page 40-  #56 & 57;  Page 42 – # 37 through 40;  Progress Book page 86 – # 7,8,11;
  • Coach Book Review work – pages to be announced…you will be able to solve and explain.

For the summative test, you should be able to

  • write numbers in scientific notation from standard form
  • write number in standard form from scientific notation
  • order and compare numbers in scientific notation
  • multiply and divide numbers in scientific notation
  • add and subtract numbers in scientific notation
  • solve word problems using scientific notation in computation and answers 

 

Due SEPTEMBER 6, 2019:

  1.  Summer assignment as the first graded homework.  NO EXCEPTIONS!  LATE HOMEWORK WILL NOT BE ACCEPTED SINCE THIS ASSIGNMENT WAS GIVEN IN JUNE. 

Due SEPTEMBER 13, 2019

  1. Review pages and computation review pages will handed in.  Be sure to follow the directions given on the first day of school. This assignment must include rationales, computations and mathematical concepts that relate to the questions.  The information for this assignment can be found in your notes as the class progresses the first week.  REMEMBER:  THIS IS A GRADED ALTERNATIVE ASSESSMENT.

ONGOING ASSIGNMENTS ON TOPIC #1 –

Laws of Exponents/Operations with Exponents/Powers and Exponents:

   Foundations in Algebra Book – pp 24 to 26

   Progress in Math Book – read pp 32 to 34; do pp 35 to 37

                                                read pp 40 to 42; do pp 43 to 45

                                                 read pp 48 to 50;  do pp 51 #1 and 2; do p 53 # 4,5,6

At least 2-3 days’ notice will be given before tests.

In addition to the work in the Progress and Foundation Books, reinforcement will be assigned from the Coach Book, and at times from worksheets.  Using all of this information will prepare you for tests.  Please remember that $10 is due to cover the cost of the additional Coach Book.  Remember that you are free to use all of this information as the class progresses to prepare for tests.  Looking forward to a productive and enjoyable year….Mr. C
