Comparing Fractions
An AWESOME PowerPoint Presentation for our BBES 3rd Graders

2. Okay… you better know this one. 
2 or 3?
Which is bigger: 3!
Phew! You got it!

3. 17! 17 or 12? Let’s try another one… Which is bigger:
Another good answer!

4. How do we figure this out?
I bet you can do this…
1 or 3 ?
Which is bigger:
How do we figure this out?

5. Well, let’s think about it like pizza!
1 4
of a pizza is ONE slice out of 4.
Like this 
and
3 4
of a pizza is THREE slices out of 4.
Like this 

6. So which is BIGGER?
1 4
3 4 ? or

7. ! 3 4 So which is BIGGER? Well this makes sense!
3 4 !
Well this makes sense!
¾ is bigger than ¼ because 3 pieces out of the 4-piece pizza is more than 1 piece out of the 4-piece pizza!
Let’s try another one. 

8. How do we figure this out?
I bet you can do this…
1 or 2 ?
Which is bigger:
How do we figure this out?

9. so it’s GOTTA be more than
WAIT A MINUTE.
2 2
Isn’t
equal to a WHOLE?
1 2
so it’s GOTTA be more than
…right?

10. Let’s prove it!
2 2
Well…
compared to
1 2

11. 2 2
We were right!
1 2
Larger

12. So which is BIGGER?
1 4
3 4 ? or

13. So which is BIGGER?
3 4 !
I could visualize that in my mind really well.
¾ is bigger than ¼ because 3 pieces out of the 4-piece pizza is more than 1 piece out of the 4-piece pizza!
Let’s try another one. 

14. NOW it’s going to get tough!
1 or 1 ?
Which is bigger:
This is WAY trickier!
The denominators are different! YIKES!

15. Well, let’s think about it like pizza again!
1 8
of a pizza is ONE slice out of 8.
Like this 
and
1 5
of a pizza is ONE slice out of 5.
Like this 

16. So which is BIGGER?
1 8
1 5 ? or

17. So which is BIGGER?
1 5 !
So this tells us that FRACTIONS are different than WHOLE NUMBERS.
Because even though 8 is bigger than 5, 1/5 is bigger than 1/8.
Let’s try a tricky one this time!

18. Think about it like pizza again!
Which is bigger?
2 or 2 ?
Think about it like pizza again!

19. of a pizza is TWO slices out of 4. of a pizza is TWO slices out of 5.
Let’s see…
2 4
of a pizza is TWO slices out of 4.
Like this 
and
2 5
of a pizza is TWO slices out of 5.
Like this 

20. So which is BIGGER?
2 4
2 5 ? or

21. So which is BIGGER?
2 4 !
So this tells us that FRACTIONS are different than WHOLE NUMBERS.
Because even though 5 is bigger than 4, 2/4 is bigger than 2/5.
Hmmm… let’s try one more.

22. Which is larger?
