WELCOME TO GRADE 10 ACADEMIC CLASS. I AM MR.BULUT. SIT WHEREVER YOU LIKE! 

TODAY'S AGENDA: Day 1-Course Intro/ Skills Review I
Great spirits have always encountered violent opposition from mediocre minds. Albert Einstein

Picture
1) Sit wherever you like; however seating arrangement will change monthly. :)
2) Let's brainstorm some classroom expectations.
3) Read MPM2D1 Course information
4) We will go through the lesson together as a class.
5) In pairs or independently, work on "Skills Review 1" Handout.


LEARNING GOAL
I will evaluate mathematical expressions and solve equations.

WARM UP



LESSON: Skills Review I

A. EVALUATING ALGEBRIC EXPRESSIONS


1. Substitute the given numbers in place of the variables. (variables: a, b, c, x, y, etc.)
2. Evaluate using the order of operations. (BEDMAS: Brackets, Exponents, Division, Multiplication, Addition, Subtraction)


Ex.1

YOUR TURN:
Ex.2

Ex.3 p=-3, evaluate 4p - 5 + 2p
Ex.4 Simplify

B. SOLVING EQUATIONS

An equation contains an equal sign. 
A solution is a value that makes the left side (LS) equal the right side (RS).
To solve an equation with one variable, isolate (leave alone) the variable.



Ex.1
x = 3 is the solution to 5x + 3 = 2(x+5) + 2 since 

LS = RS. 
Want to check? Well, let's sub 3 for "x" on each side.

LS= 5x + 3                                     RS = 2(x+5) + 2                        
    = 5(3) + 3                                        = 2(3+5) + 2                           = 15 + 3                                           = 2(8) + 2
    = 18                                                 = 16 + 2 

                                                           = 18
  

YOUR TURN: Volunteers for the solutions.
Ex.2 Is x = 5 a solution for 2x - 4 = 5?  
Ex.3 Solve 6x + 8 = 4x - 10
Ex.4  Solve 5(x + 2) = x + 6(x - 3)
Ex.5  Solve 1/2 (x - 1) = 1/4 (x + 1)
