Fractions on a Number Line — Answer Key
Part A: Multiple Choice
Circle the best answer for each question.
1. In Grade 3, which fraction sits between 3/4 and 5/4 on a fourths number line extended past 1?
A) 2/4
B) 4/4
C) 6/4
D) 7/4
4/4 is between 3/4 and 5/4 on a fourths number line, equal to 1 in Grade 3.
2. In Grade 3, comparing the same point on different lines, 1/2 equals which fraction on a sixths line?
A) 1/6
B) 2/6
C) 3/6
D) 5/6
3/6 equals 1/2 because both mark the midpoint of 0 and 1 on a Grade 3 number line.
3. In Grade 3, where does the fraction 8/3 land on a thirds number line extended past 2?
A) Between 1 and 2
B) Exactly at 2
C) Two ticks past 2
D) Three ticks past 2
8/3 equals 2 and 2/3, which is two ticks past 2 on a thirds number line in Grade 3.
4. In Grade 3, on an eighths line, which fraction is equivalent to 1/2?
A) 2/8
B) 3/8
C) 4/8
D) 5/8
4/8 reduces to 1/2, so both mark the midpoint of 0 and 1 in Grade 3.
Part B: Fill in the Blank
Write the correct answer on each line.
1. In Grade 3, on a fourths line, the fraction 6/4 lands between 1 and 2.
6/4 equals 1 and 2/4, which sits between 1 and 2 on a fourths line in Grade 3.
2. In Grade 3, the missing fraction between 1/6 and 3/6 on a sixths line is 2/6.
2/6 sits between 1/6 and 3/6, filling the missing tick on a sixths line in Grade 3.
3. In Grade 3, comparing 2/3 and 2/4, the greater fraction is 2/3.
2/3 sits past 1/2 while 2/4 equals 1/2, so 2/3 is greater in Grade 3.
4. In Grade 3, the fraction equivalent to 2 on a thirds number line is 6/3.
6/3 equals 2 because each 3/3 equals 1 whole, so 6/3 is two wholes in Grade 3.
5. In Grade 3, the missing fraction between 4/8 and 6/8 on an eighths line is 5/8.
5/8 sits between 4/8 and 6/8 on an eighths number line, filling the missing tick in Grade 3.
