First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 400 to 500 and is split into 4 equal spaces. The arrow is 1 space along from 400. What number does the arrow point to?
Answer: 425
- Each space is (500 − 400) ÷ 4 = 25
- 400 + 1 × 25 = 425
2.A number line goes from 200 to 280 and is split into 4 equal spaces. The arrow is 1 space along from 200. What number does the arrow point to?
Answer: 220
- Each space is (280 − 200) ÷ 4 = 20
- 200 + 1 × 20 = 220
3.What number is halfway between 40 and 380?
Answer: 210
- 380 − 40 = 340; half of that is 170
- 40 + 170 = 210
4.A number line goes from 400 to 500 and is split into 4 equal spaces. The arrow is 3 spaces along from 400. What number does the arrow point to?
Answer: 475
- Each space is (500 − 400) ÷ 4 = 25
- 400 + 3 × 25 = 475
5.A number line goes from 6,000 to 7,250 and is split into 5 equal spaces. The arrow is 2 spaces along from 6,000. What number does the arrow point to?
Answer: 6,500
- Each space is (7,250 − 6,000) ÷ 5 = 250
- 6,000 + 2 × 250 = 6,500
6.What number is halfway between 150 and 590?
Answer: 370
- 590 − 150 = 440; half of that is 220
- 150 + 220 = 370
7.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
8.A number line goes from 0 to 400 and is split into 4 equal spaces. The arrow is 2 spaces along from 0. What number does the arrow point to?
Answer: 200
- Each space is (400 − 0) ÷ 4 = 100
- 0 + 2 × 100 = 200
9.What number is halfway between 20 and 60?
Answer: 40
- 60 − 20 = 40; half of that is 20
- 20 + 20 = 40
10.A number line goes from 600 to 700 and is split into 4 equal spaces. The arrow is 1 space along from 600. What number does the arrow point to?
Answer: 625
- Each space is (700 − 600) ÷ 4 = 25
- 600 + 1 × 25 = 625
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.
