### Eureka Math Grade 3 Module 7 Lesson 32 Problem Set Answer Key

Question 1.
Look at the circles you shaded today. Glue a circle that is about one-half shaded in the space below.
a. Explain the strategy you used to shade in one-half of your circle.
a. I have first check the number of shaded parts and unshaded parts in the given circle. Later, I have tried to balance the count between the parts.

b. Yes, my circle is one-half shaded because the count of shaded and unshaded parts in the circle are equal.

Explanation:
a.

I have first check the number of shaded parts and unshaded parts in the given circle. Later, I have tried to balance the count between the parts.

b. Yes, my circle is one-half shaded because the count of shaded and unshaded parts in the circle are equal.

Question 2.
Julian shades 4 circles as shown below.

a. Write the letters of the circles that are about one-half shaded.
Circle _______
c. Choose one circle that you did not list in Part (a), and explain how it could be changed so that it is about one-half shaded.
Circle _______

a. Circle A,C and D the letters of the circles that are about one-half shaded.

b. Well, Circle A is one-half sided shaded because when u half fold it, u get to notice that one part is shaded and other half part not shaded.

c. Circle C is not one-half sided shaded. You can make it into one- half shaded by shading the part which is not shaded.

Question 3.

a. Divide the circle into 4 equal parts.
c. Erase a small circle from each shaded part.
d. Estimate to draw and shade 2 circles in the unshaded parts that are the same size as the circles you erased in Part (c).
a.

b.

c.

d.

Explanation:
a.
Circle is divided into four equal parts and labelling the parts ends as A,B,C,D with O as center.

b.
ABD Half part of ABCD circle is been shaded using blue color.

c.
A small portion of circles are erased from ABD shaded part of the circle.

d.
A small portion which are erased from shaded part of the circle are shaded in the unshaded part of the circle.

Question 4.
4. Did you shade in one-half of the circle in Problem 3? How do you know?
Yes, I have shaded in one-half of the circle in Problem 3 because half part of a circle is semi- circle( one-half), where I have shaded it. Number of shaded parts to unshaded parts are equal.

Explanation:
Half part in a circle is semi-circle. Here, circle half part is ABD which is been shaded in blue color and other unshaded.

Riddian shades a circle as shown below.

Question 1.
Yes, Riddian’s shape is about one-half shaded. I know it because number of shaded regions and number of unshaded regions are same in the shape.

Explanation:

Question 2.
Estimate to shade about one-half of the circle in an unusual way.

Explanation:

The circle is half shaded with grey color with different shapes erased and half part is unshaded with different shapes shaded in it. Shading part and the different shapes in it are the same in shading and unshaded way.

Question 1.

Explanation:
Number of shaded parts to that of number of unshaded parts are equalized to make it one-half shaded.

Question 2.
Choose one of the circles in Problem 1, and explain how you know it’s about one-half shaded.
Circle _____
I have taken “a” circle in the problem1. I know its not one half shaded because the number of shaded parts are not equal to unshaded parts in the circle.

Explanation:

Question 3.
Can you say the circles in Problem 1 are exactly one-half shaded? Why or why not?
Well, all circles in problem 1 are not one-half shaded because the shaded parts are not equal to unshaded parts in the respective circles.

Explanation:

Question 4.
Marissa and Jake shade in circles as shown below.
