HMH Into Math Grade 3 Module 13 Review Answer Key
Vocabulary
Question 1.
Write each number under the category that it matches.
Answer:
– A fraction consists of two numbers (a/b), a numerator and a denominator. The number written at the top is the numerator, and the one written at the bottom is the denominator.
– There are three major types of fractions: They are:
– named as proper fractions (or the fractions less than one and greater than 0, with numerator less than denominator),
improper fractions (or the fractions more than one or equal to one with a numerator greater than or equal to the denominator), and mixed fractions (a combination of a whole number and a proper fraction).
Concepts and Skills
Question 2.
Draw lines to divide the shape into eighths.
Shade 1 part of the shape. Write the fraction that names the shaded part.
Answer:
The term ‘fraction’ represents a quantity that is part of an entire object.
we have an outsized square that the square is divided into 8 equal parts. Then each portion of the part is merely 1/8th of the total quantity of the square. Here, 1/8 = fraction.
Numerator: The top half of a fraction that represents the number of parts you have got. Within the above example, 1 is the numerator.
Denominator: The bottom half of a fraction represents the amount into which the entire object is split. Within the above example, 8 is the denominator.
The question asked was to shade 1 part and the fraction of that shaded part is 1/8.
Question 3.
Use Tools Each triangle represents \(\frac{1}{2}\) of a whole square. How many triangles do you need to make \(\frac{7}{2}\)? Tell what strategy or tool you will use to solve the problem, explain your choice, and then find the answer.
(A) 6
(B) 7
(C) 8
(D) 14
Answer:
Question 4.
Which fraction names the shaded part?
(A) \(\frac{1}{4}\)
(B) \(\frac{1}{6}\)
(C) \(\frac{5}{6}\)
(D) \(\frac{6}{6}\)
Answer: Option D is correct
Explanation:
The number of parts=6
The fraction of each part=1/6
Likewise, 6 parts:1/6+1/6+1/6+1/6+1/6+1/6
Total fraction=6/6.
Question 5.
Which fraction is represented by the point on the number line?
(A) \(\frac{1}{1}\)
(B) \(\frac{1}{2}\)
(C) \(\frac{1}{3}\)
(D) \(\frac{1}{4}\)
Answer:
To plot fractions on the number line, follow the steps given below:
Step 1: Draw a number line of a suitable length.
Step 2: check the fractions once. If the given fraction is a proper fraction then mark points 0 and 1 on the number line. If it is an improper fraction, then we have to convert it into a mixed fraction, and then mark two integers between those the given fraction lies.
Step 3: Draw an equal number of parts of the numbers marked in step 2 which will be equal to the denominator of the fraction.
Step 4: Starting from the left point, count forward the number of parts shown by the numerator.
Step 5: Mark the point on the line.
Question 6.
Which number line shows \(\frac{3}{3}\)?
Answer: Option A is correct.
Because the number line has 3 lines 0/3, 1/3, 2/3, 3/3.
To plot fractions on the number line, follow the steps given below:
Step 1: Draw a number line of a suitable length.
Step 2: check the fractions once. If the given fraction is a proper fraction then mark points 0 and 1 on the number line. If it is an improper fraction, then we have to convert it into a mixed fraction, and then mark two integers between those the given fraction lies.
Step 3: Draw an equal number of parts of the numbers marked in step 2 which will be equal to the denominator of the fraction.
Step 4: Starting from the left point, count forward the number of parts shown by the numerator.
Step 5: Mark the point on the line.
Question 7.
Which is the length of the craft stick to the nearest half-inch?
(A) 4 inches
(B) inches
(C) 5 inches
(D) 5\(\frac{1}{2}\) inches
Answer: Option D is correct.
Explanation:
If the craft stick was 5.2 inches then the nearest length will be 5 1/2 inches.
We need to check this firstly, we have to know the standard stick measurements and wide measurements.
Standard stick measurements are 4.475 inches
The standard wide measurements are 0.375 inches.
I think it is more than 5 inches so the nearest inch will be 5 1/2 inches.
