Slide 5 - Tekstslide

What to do


I got the questions right!             Work on pink (challenge) or blue slide                                                                                     (Intermediate) in  LessonUp   

- I had 1-2 mistakes                            Do problems on the board

Slide 6 - Tekstslide

Equations with fractions
What is the inverse operation of a fraction? 


5x=4

Slide 7 - Tekstslide

Equations with fractions
What is the inverse operation of a fraction? 
Multiplication!
You apply inverse operations on BOTH SIDES
So to get rid of a fraction: You multiply by the denominator 


5x=4

Slide 8 - Tekstslide

Equations with fractions
If there are more inverse operations (2-step equation), 
Get rid of the fraction FIRST
2(x+1)=7

Slide 9 - Tekstslide

Equations with fractions
What is the inverse operation of a fraction? 
Multiplication!
You apply inverse operations on BOTH SIDES 


5x=4

Slide 10 - Tekstslide

Equations with fractions
If there are more inverse operations (2-step equation), 
Get rid of the fractions (do multiplication) FIRST

Slide 11 - Tekstslide

Equations with fractions
If there are more inverse operations (2-step equation), 
Get rid of the fractions (do multiplication) FIRST
Use the lowest common multiple


Slide 12 - Tekstslide

Equations with fractions
If there are more inverse operations (2-step equation), 
Get rid of the fractions (do multiplication) FIRST
Use the lowest common multiple


Slide 13 - Tekstslide

Equations with fractions
f

LCM of denominators = 

Slide 14 - Tekstslide

What to do
Open this LessonUp on your device. 
Work on the slides with the appropriate color: 

- I really want a challenge!                                                                         Slide 18
- I think a bit more practice will help me!                                            Slide 17
- I think more practice will help me! I would like some help.     Slide 16

Do problems: 3, 5, 6, 9, 13, 14

Slide 17 - Tekstslide

Slide 18 - Tekstslide

Challenge
Find the Splodge extension sheet

ManageBac > Files > Unit 3 > equations with fractions challenging

Slide 19 - Tekstslide

Slide 20 - Tekstslide

Word problems Murder Mystery
Did you find the culprit?
Don't spoil it for the others!! secretly tell the teacher to check if you are correct

You can: 
- help the people in your group solving the questions
- continue with the circuit training worksheet from yesterday 
- Work on Files > Unit 3 > Challenging Multistep equations 2

Slide 21 - Tekstslide

Partner practice
- You both work on you questions individually
- You check the answers together (if you have the same answers with the same number questions, it should be correct)
- If the answers are NOT the same, analyze for errors
