Mr. Hagemann ate 4/5 slices of pizza.
How many slices was the whole pizza cut into?
5 Slices. (Look at the denominator).
Is this true 3/3 > 5/4? Why or why not?
No because 3/3 equals 1 and 5/4 is greater than one since the numerator is greater than the denominator.
Use the benchmark fraction 1/2 to compare 2/8 and 9/10. Which one is greater?
9/10
Order these fractions from least to greatest 1/3 3/5 4/8
1/3 4/8 3/5
What are 2 fractions equal to 9/9
Any fraction that has the same number in the numerator and the denominator.
If Mrs. DiCataldo had 3 slices of pizza and the pizza was cut into 9 slices, what fraction of the pizza did she eat?
3/9 of the pizza.
Is this true 2/8 = 1/4? Why?
Yes because when you divide 2/8 by 2/2, it equals 1/4.
Use 1 to determine which one is greater, 4/5 or 5/4? Explain.
5/4

No because 3/6 equals 1/2, a benchmark fraction, which is further from zero on the number line than 2/8.
Use the benchmark fraction 1/2 to determine if 4/8 is greater than 2/6. Explain.
4/8 is greater than 2/6 because 4 is half of 8, but 2 is less than 3 which is half of 6.
Explain why 8/7 is greater than 1

1/9 of the protein bar. Poor Robin.
Is this true? Benchmark fractions are the only way to compare fractions. Explain.
No. Models, number lines, multiplication, and division can also be used as strategies.
Use the benchmark fraction 1/2 to determine which is less than half.
5/4 1/4 3/8 2/3 2/12
1/4 3/8 2/12
Explain why 2/3 is less than 1.
2/3 the numerator is not greater than then denominator or the numerator is not the same number as the denominator.
Explain why 5/5 is equivalent to 8/8.
5 divided by 5 = 1
8 divided by 8 = 1
Both equal 1 whole even though the parts for 5ths are greater than 8ths

No, 9/8 is greater than one, 11/12 is less than 1.
Jingles meowed, "I know 1/4 is less than 1/2, so that means 3/12 is less than 1/2." Does Jingles's reasoning make sense? Explain.
Yes, Jingles is one smart kitty.
1/4 X 3/3 = 3/12 and both are less than 1/2.
Explain why 7/7 is equal to 1.
7/7 is equal to 1 because the numerator is the same number as the denominator.
