Fractions on a Number Line — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. Grade 3: On a fourths number line from 0 to 2, where does 5/4 sit?
A) One whole plus one quarter past 1
B) Halfway between 0 and 1
C) At the point 1
D) Past 2 by one quarter
Five fourths equals one whole (4/4) plus one more fourth, so it sits 1/4 past 1.
2. Grade 3: Is 7/4 closer to 1 or closer to 2 on the number line?
A) Closer to 2
B) Closer to 0
C) Closer to 1
D) Exactly halfway
Seven fourths is only 1/4 from 2 but 3/4 from 1, so it is closer to 2.
3. Grade 3: Which fraction equals exactly 1 whole on a thirds number line?
A) 3/3
B) 2/3
C) 1/3
D) 4/3
Three thirds is one whole because three 1/3 units fill 0 to 1 on the line.
4. Grade 3: On a halves line from 0 to 2, where is 3/2?
A) Halfway between 1 and 2
B) Halfway between 0 and 1
C) At the point 2
D) At the point 0
Three halves equals one whole plus one half, landing halfway between 1 and 2.
Part B: Fill in the Blank
Write the correct answer on each line.
1. Grade 3: On a fourths line, 5/4 sits one fourth past the point 1.
Four fourths equals 1, so one more fourth lands 1/4 past the whole 1.
2. Grade 3: The fraction 7/4 is closer to 2 than to 1 on the number line.
Seven fourths is only 1/4 from 2 but 3/4 from 1, so it is closer to 2.
3. Grade 3: On a thirds line, the fraction 4/3 is one third past 1.
Four thirds equals one whole plus one third, landing 1/3 past 1 on the line.
4. Grade 3: On a halves line, 3/2 lands halfway between 1 and 2.
Three halves equals 1 plus 1/2, placing it halfway between the points 1 and 2.
5. Grade 3: Between 6/4 and 2, the fraction equal to 2 on a fourths line is 8/4.
Eight unit fractions of 1/4 equal two wholes, so 8/4 sits at the point 2.
