Fractions on a Number Line — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. In Grade 3, on a fourths number line extended past 1, where does 5/4 land?
A) Between 0 and 1/4
B) Exactly at 1
C) One tick past 1
D) Two ticks past 1
Five jumps of 1/4 equals 1 whole plus one more 1/4, so 5/4 is one tick past 1 in Grade 3.
2. In Grade 3, on a thirds number line extended past 1, where does 7/3 land?
A) Between 0 and 1
B) Exactly at 2
C) One tick past 2
D) One tick before 2
7/3 equals 2 and 1/3, so it lands one tick past 2 on a thirds number line in Grade 3.
3. In Grade 3, which fraction on a sixths line lies between 2/6 and 4/6?
A) 1/6
B) 3/6
C) 5/6
D) 6/6
3/6 sits between 2/6 and 4/6 on a sixths number line, making it the missing point in Grade 3.
4. In Grade 3, comparing points on number lines, which fraction is greater: 2/3 or 2/6?
A) 2/6 is greater
B) 2/3 is greater
C) They are equal
D) It cannot be compared
2/3 lands past 1/2 while 2/6 lands before 1/2, so 2/3 is greater in Grade 3.
Part B: Fill in the Blank
Write the correct answer on each line.
1. In Grade 3, on a fourths number line, the fraction 4/4 equals the whole number 1.
4/4 uses four out of four equal parts, which is the whole, equal to 1 in Grade 3.
2. In Grade 3, on a thirds number line, 6/3 lands at the whole number 2.
Each 3/3 is 1, so 6/3 is two wholes, landing exactly at 2 in Grade 3.
3. In Grade 3, on a fourths line, the fraction one tick before 1 is 3/4.
3/4 is the tick just before 4/4, so it sits one tick before 1 on a Grade 3 fourths line.
4. In Grade 3, comparing 3/4 and 3/6, the greater fraction is 3/4.
3/4 is past the midpoint while 3/6 equals 1/2, so 3/4 is greater in Grade 3.
5. In Grade 3, on a thirds number line, 5/3 lies between the whole numbers 1 and 2.
5/3 equals 1 and 2/3, which sits between 1 and 2 on a Grade 3 number line.
