6th Bronte & 6th Neruda
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
Objective: Use order of operations.
Activate Prior Knowledge:
Solve.
- 3 + (9 + 7)=
- (7-3) + 4=
- 4 x (2 + 5)=
- (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
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
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
Objective: Use mathematical properties to find sums, differences, products, and quotients.
Activate Prior Knowledge:
Solve by using mental math.
- d + 13 = 33
- 25 - g = 17
- 6m = 54
- 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.

Activate Prior Knowledge
Find the product. Show your work.
- 9.06 x 62=
- 17.37 x 2=
- 38.2 x 6=
- 9.9 x 92=
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.
