1. Warm Up
Complete the multiplication chart.
-Start with 1-10 and continue if time.
-You have 5 minutes!

2. Total your Score!

3. Mini Refresher:
-An equation is a math statement with an equal sign.
Example: x + 2 = 8
-A variable is the letter in the math statement.
Example: The variable for the above equation is "x"
-"Inverse" means opposite

4. Match the following operations with their inverse operation:
Multiplication
Addition
Subtraction
Division
Addition
Division
Multiplication
Subtraction

5. We can solve equations by using inverse (opposite) operations!
Working backwards can also be used in many other real life situations...

6. For example...

7. 3 2 1

8. We can build and unbuild equations using the same process:   

11. ? ? ? ? ?

12. 

13. Solving one-step equations only requires one step
Solving one-step equations only requires one step! They will always be in one of the following forms:
ax = b
a + x = b
x - a = b
x = b a

14. Practice:

17. Solving a two-step equation requires two steps! For example:
*You must get the variable alone! A.K.A get everything on the other side.
*Start furthest from x and work your way in.

18. 

19. Practice:

21. 

22. 

23.    

24. Independent Work:
Pages #8, 10, 11, 12, 14, 15
# 16-18, 20
Take it Further # 24
-You MUST choose a total of 5 questions to do

25. Wrap Up:
-Choose a coloured dot to indicate your understanding today:
-Red = Hard
-Yellow = Medium
-Green = Easy
