### Eureka Math Grade 3 Module 5 Mid Module Assessment Task Answer Key

Question 1.

Natalie folded 1 whole fraction strip as pictured above.

a. How many equal parts did she divide the whole into?

b. Label each equal part with a unit fraction.

c. Identify the fraction of the strip she shaded.

d. Identify the fraction of the strip she did not shade.

Answer:

a. The Total Number of Equal parts are 8 .

b.

c. Fraction of each shaded strip = \(\frac{1}{8}\)

Total Number of shaded strips = 3

So, Total fraction of shaded strip = \(\frac{1}{8}\) + \(\frac{1}{8}\) +\(\frac{1}{8}\) = \(\frac{3}{8}\)

d . Fraction of each unshaded strip = \(\frac{1}{8}\)

Total Number of shaded strips = 5

So, Total fraction of unshaded strip = \(\frac{1}{8}\) + \(\frac{1}{8}\) +\(\frac{1}{8}\) +\(\frac{1}{8}\) +\(\frac{1}{8}\) = \(\frac{}{8}[5/latex]

Question 2.

Draw 2 rectangles the same size. Each rectangle represents 1 whole.

a. Partition each rectangle into 3 equal parts. Shade and label a fraction greater than 1.

b. Draw a number bond that shows 1 whole rectangle as 3 unit fractions.

Answer:

a

Explanation :

The Each Rectangle strip is divided into 3 equal parts and 4 parts are shaded as shown in above figure which is greater than 1 whole .

Answer :

b

Question 3.

The bakery had a chocolate cake and a vanilla cake that were exactly the same size. Mr. Chu bought 1 fourth of the chocolate cake. Mrs. Ramirez bought 1 sixth of the vanilla cake. Who bought a larger piece of cake? Explain your answer using words, pictures, and numbers.

Answer:

Explanation :

From the above figure we notice that the piece of chocolate cake is bigger than vanilla cake . That means Mr.chu bought larger piece cake than Ramirez .

Question 4.

Natalie explained, “My drawing shows a picture of [latex]\frac{3}{2}\).” Kosmo says, “It looks like a picture of \(\frac{3}{4}\) to me.”

a. Show and explain how they could both be correct by choosing different wholes. Use words, pictures, and numbers.

b. Natalie said to Kosmo, “One part can represent either 1 half or 1 fourth. That must mean \(\frac{1}{2}\) = \(\frac{1}{4}\).” Do you agree with Natalie? Use words, pictures, and numbers to explain your reasoning.

Answer a :

Explanation :

Both are right because it depends on the consideration of 1 whole .

Answer b :

Explanations :

Natalie is wrong because the wholes are not of identical shape and size .The wholes should be same to compare the fractions .
