Today we practiced Interger Multiplication using Arcademic Skill Builder (see link in Thursday's post).

We corrected the PreTest and 6.7.

Test Wednesday.
Review all material related to the Addition, Subtraction, Multiplication and Division of Integers. (see posts below)

Thurs Oct 27

Today we participated in the School-Wide "Go LOW or go HOME" activity.  Then we explored some elegant solutions to the problems on the PreTest.

Tomorrow there will be a free period/party - Bring any treats or music you'd like.

Homework: For Monday - Finish all of 6.7, both sides.

Today class was cut short by a Skills Canada presentation - The presenter reminded us that Math is important!!

Homework - Do PreTest - both sides.  If you did not finish 6.7a,b,c of both sides it is now overdue.

Monday Oct 24th - Caleb's birthday

HW - Finish all work about integers except half of sheet with two faces.

Fri Oct 21, 2011 = Subtracting Integers

Today we took an oath -
I _____________ , no longer need to subtract.... I will ADD the OPPOSITE.

Homework: First half of "Adding and Subtracting Integers - C"

Wed Oct 19 - a tasty class

Today we explored the addition, subtraction, multiplication and division of integers using candy.

Homework: Complete all questions on "Thinking about Integers Mini-Assignment"

Having trouble explaining how to do addition and subtraction??

Today we finished the Test #1 and learned how to solve KenKen.

HW = Do at least one new KenKen (or spend at least 20 minutes trying)

Thurs Oct 13 - Test tomorrow

After much debate class 7-8 has decided on having a free period the day of the Hallowe'en Dance and the test tomorrow.
See yesterday's post for the topics covered on the test.

HW - Finish Pretest - due Thursday.

Bonus - Finish Daphne Dogcatcher sBEDMAS problems.  Please show your work on the back of the sheet, attach scrap paper if you run out of room.

 Enjoy a Thanksgiving Weekend without homework if you are caught up on all of your work.

TEST Thursday  Friday Oct 13 14, 2011
Topics
Divisibility rules for 2,3,4,5,6,8,9
Factoring (ex. 24 has the factors 1 ,2 , 3 ,4 ,6 ,8 ,12, 24)
Prime Factoring (24 = 2 x 2 x 2 x 3)
Using Prime factoring to find the LCM & GCF and solve word problems
Estimating square roots
Exponents
Using sBEDMAS
Multiplying and dividing using decimals

Thurs Oct 6 - More sBEDMAS

More sBEDMAS

Homework:  1.3 #3, 1.8 #4.
If you are finished both, do 2 Daphne Dogcatcher Order of Operations.

Overdue: 1.1, 1.2, 1.3, #1, 2 & 3 of 1.8

Wed Oct 5 - sBEDMAS

Today we looked at word problems using GCF and LCM (see back side of 1.3).

We learned that sBEDMAS means:
s - Square Roots
B - Brackets
E - Exponents
D - Division  and M - Multiplication (left to right)
A - Addition and  S - Subtraction (left to right)

HW - 1.8 Order of Operations #1, #2 and #3
Overdue - 1.1, 1.2, 1.3  These need to be finished!!!


Wanna play some Math games to practice sBEDMAS -

Oct 4 - Using Prime Factoring to find the LCM (Lowest Common Multiple) and GCF (Greatest Common Factor)

Today we looked at how to use Prime Factoring to find the LCM (Lowest Common Multiple) and GCF (Greatest Common Factor) of two numbers.

For example
8 = 2 x 2 x 2
12 = 2 x 2 x 3
Their GCF 4.  It is the product of the prime factors they have in common  2 x 2
Their LCM is 24.  It is the product of the prime factors they share (2 x 2) times all of the factors they don't share (x 2 x3).  So their LCM is 2 x 2 x 2 x 3

Homework:  1.3 Questions #1 and #2.
1.1 and 1.2 are overdue.
