Number Lines — Answer Key
Part A: Fill in the Blank
Write the missing word or number on each line.
1. Start at 10 and take 3 jumps of 5 to the right. You land on 25.
Three jumps of 5 add 15, so 10 plus 15 is 25 on the number line.
2. From 0, 4 jumps of 5 end at 20.
Four hops of 5 equal 20, so you land on 20 starting at 0.
3. Start at 30 and take 2 jumps of 5. You land on 40.
Two jumps of 5 add 10, so 30 plus 10 is 40.
4. From 45, jumping 5 to the right 3 times ends at 60.
Three hops of 5 add 15, so 45 plus 15 lands on 60.
5. Start at 5 and take 5 jumps of 5. You land on 30.
Five jumps of 5 add 25, so 5 plus 25 is 30.
6. From 50, two jumps of 5 to the right end at 60.
Two hops of 5 add 10, so 50 plus 10 is 60 on the line.
7. Start at 70 and take 4 jumps of 5. You land on 90.
Four hops of 5 add 20, so 70 plus 20 is 90.
8. From 20, 3 jumps of 5 to the right end at 35.
Three jumps of 5 add 15, so 20 plus 15 is 35 on the number line.
9. Start at 65 and take 2 jumps of 5. You land on 75.
Two hops of 5 add 10, so 65 plus 10 is 75.
Part B: Matching
Match each item on the left to the correct answer on the right.
1. Match each item to its correct answer.
Starts at 25 and jumps 3 hops of 5
→ 35
40
Starts at 40 and jumps 4 hops of 5
→ 60
60
Starts at 5 and jumps 6 hops of 5
→ 40
35
Starts at 55 and jumps 5 hops of 5
→ 80
80
Each left item tells you the start and how many hops of 5 to take; add 5 per hop to find the end.
