6th Bronte & 6th Neruda

Objective: Use order of operations.

Application:

p.45(6-15)

Review order of operations, remember to use PEMDAS, solve each expression one under the other. It is very important that you organize your work.

Always show your process, I will not correct if you only provide the answers.

Tomorrow I will be collecting the division worksheet.

6th Bronte & 6th Neruda

Quote: Better a diamond with a flaw than a pebble without.- Confucius.

Objective: Use order of operations.

Activate Prior Knowledge:

Solve.

  1. 3 + (9 + 7)=
  2. (7-3) + 4=
  3. 4 x (2 + 5)=
  4. (9 - 2) x 7=

New Knowledge:

To evaluate an expression that contains more than one operation you use rules called order of operations.

We use PEMDAS to remember the operations:

P: parenthesis

E: exponents

M: multiplication

D: division

A: addition

S: subtraction

Multiplication and division is always the first operation from left to right.

Addition and subtraction is always the first operation from left to right.

Application:

p.45 (6-15)

6th Bronte & 6th Neruda

Quote: We are made wise not by the recollection of our past, but by the responsibility for our future. ~George Bernard Shaw

Activate Prior Knowledge:
Find the product.
1. 3 x 3 =
2. 6 x 6 =
3. 4 x 4 x 4 =
4. 2 x 2 x 2 x 2 =
5. 9 x 9 x 9 =

New Knowledge:
An exponent is a number that tells how many times a base is used as a factor.

Base^Exponent

For example: 2^3 = 2 x 2 x 2 = 8

The following rules apply to numbers with exponents 0, 1, 2, and 3.
▫ Any number (except 0) raised to the zero power is equal to 1. Ex. 1490 = 1
▫ Any number raised to the first power is always equal to itself. Ex. 81 = 8
▫ If a number is raised to the second power, we say it is squared. Ex. 32 is read as three squared
▫ If a number is raised to the third power, we say it is cubed. Ex. 43 is read as four cubed

Application: p.41 (8-32).
Homework: p.H3(1-8)

6th Bronte & 6th Neruda

Quote: To be upset over what you don't have is to waste what you do have. ~Ken S. Keyes

Objective: Use mathematical properties to find sums, differences, products, and quotients.

Activate prior knowledge:
Name the property shown.
a) 7 x 2 = 2 x 7
b) 6 + 3 = 3 + 6
c) 3( 9 + 7 )= (3 x 9) + (3 x 7)
d) 6 + (1 + 4) = (6 +1) + 4
e) (4 x 3) x 5= 4 x (3 x 5)

New Knowledge:
Reinforce math properties. Discuss the following properties of multiplication and addition:
▫ Identity Property of Zero
▫ Identity Property of One

Application:
Complete p.38(3-18)
p. H2 (1-9)

Review multiplication tables.

6th Bronte & 6th Neruda

Quote: When you blame others, you give up your power to change.- Author Unknown

Objective: Use mathematical properties to find sums, differences, products, and quotients.

Activate Prior Knowledge:
Solve by using mental math.

  1. d + 13 = 33
  2. 25 - g = 17
  3. 6m = 54
  4. 9 = x ÷ 11

Variables are letters that represent numbers.

New Knowledge:

One way to find the sum or product mentally is to use a number property.

Commutative Property:

  • Of Addition: Numbers can be added in any order without changing the sum.

Ex. 45 + 29 + 55 = 29 +45 +55

129 = 129

  • Of Multiplication: Numbers can be multiplied in any order without changing the product.

Ex. 5 x 3 x 8 = 5 x 8 x 3

120 = 120

Associative Property:

  • Of Addition: Addends can be grouped differently; the sum is always the same.

Ex. (45 + 29) + 55 = 45 + (29 +55)

129 = 129

  • Of Multiplication: Factors can be grouped differently; the product is always the same.

Ex. (5 x 3 ) x 8 = 5 x (3 x 8)

120 = 120

Distributive Property:

5 (8 + 2) = (5 x 8) + (5 +2)

5(10) = 40 + 10

50 = 50


Application: p.38(3-18) We are going to continue tomorrow


Reflection:Properties help us…

Reinforcement tomorrow in 6th Bronte from 2:45 - 3:25 p.m.

6th Bronte and Neruda

Quote: If you don't like something change it; if you can't change it, change the way you think about it.- Mary Engelbreit

Objective: Multiply Decimals by Whole Numbers

New Knowledge

To multiply Decimals by Whole Numbers, do your multiplication normally like you do with whole numbers; when you find the product place the decimal point by counting the decimal places in the original exercises.

Application

Find the products. Show your work.
