Year 3 Number Lines Worksheet — Level 2 — Practice Set 4 — Answers
First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 200 to 400 and is split into 4 equal spaces. The arrow is 3 spaces along from 200. What number does the arrow point to?
Answer: 350
- Each space is (400 − 200) ÷ 4 = 50
- 200 + 3 × 50 = 350
2.A number line goes from 100 to 225 and is split into 5 equal spaces. The arrow is 3 spaces along from 100. What number does the arrow point to?
Answer: 175
- Each space is (225 − 100) ÷ 5 = 25
- 100 + 3 × 25 = 175
3.What number is halfway between 130 and 610?
Answer: 370
- 610 − 130 = 480; half of that is 240
- 130 + 240 = 370
4.A number line goes from 800 to 900 and is split into 4 equal spaces. The arrow is 3 spaces along from 800. What number does the arrow point to?
Answer: 875
- Each space is (900 − 800) ÷ 4 = 25
- 800 + 3 × 25 = 875
5.A number line goes from 200 to 300 and is split into 5 equal spaces. The arrow is 2 spaces along from 200. What number does the arrow point to?
Answer: 240
- Each space is (300 − 200) ÷ 5 = 20
- 200 + 2 × 20 = 240
6.What number is halfway between 70 and 570?
Answer: 320
- 570 − 70 = 500; half of that is 250
- 70 + 250 = 320
7.A number line goes from 9,000 to 10,000 and is split into 4 equal spaces. The arrow is 2 spaces along from 9,000. What number does the arrow point to?
Answer: 9,500
- Each space is (10,000 − 9,000) ÷ 4 = 250
- 9,000 + 2 × 250 = 9,500
8.A number line goes from 6,000 to 8,500 and is split into 10 equal spaces. The arrow is 4 spaces along from 6,000. What number does the arrow point to?
Answer: 7,000
- Each space is (8,500 − 6,000) ÷ 10 = 250
- 6,000 + 4 × 250 = 7,000
9.What number is halfway between 270 and 510?
Answer: 390
- 510 − 270 = 240; half of that is 120
- 270 + 120 = 390
10.A number line goes from 600 to 700 and is split into 4 equal spaces. The arrow is 3 spaces along from 600. What number does the arrow point to?
Answer: 675
- Each space is (700 − 600) ÷ 4 = 25
- 600 + 3 × 25 = 675
Marking tips
- Give credit for correct method even when the final answer slips — the working shows where the thinking went right.
- For open-ended tasks, use the success criteria as a checklist rather than looking for one "right" answer.
- Celebrate what went well first, then pick one thing to work on next.
