First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 400 to 650 and is split into 10 equal spaces. The arrow is 3 spaces along from 400. What number does the arrow point to?
Answer: 475
- Each space is (650 − 400) ÷ 10 = 25
- 400 + 3 × 25 = 475
2.A number line goes from 4,000 to 5,000 and is split into 4 equal spaces. The arrow is 1 space along from 4,000. What number does the arrow point to?
Answer: 4,250
- Each space is (5,000 − 4,000) ÷ 4 = 250
- 4,000 + 1 × 250 = 4,250
3.What number is halfway between 90 and 270?
Answer: 180
- 270 − 90 = 180; half of that is 90
- 90 + 90 = 180
4.A number line goes from 800 to 1,000 and is split into 10 equal spaces. The arrow is 1 space along from 800. What number does the arrow point to?
Answer: 820
- Each space is (1,000 − 800) ÷ 10 = 20
- 800 + 1 × 20 = 820
5.A number line goes from 4,000 to 6,500 and is split into 10 equal spaces. The arrow is 9 spaces along from 4,000. What number does the arrow point to?
Answer: 6,250
- Each space is (6,500 − 4,000) ÷ 10 = 250
- 4,000 + 9 × 250 = 6,250
6.What number is halfway between 30 and 50?
Answer: 40
- 50 − 30 = 20; half of that is 10
- 30 + 10 = 40
7.A number line goes from 100 to 225 and is split into 5 equal spaces. The arrow is 2 spaces along from 100. What number does the arrow point to?
Answer: 150
- Each space is (225 − 100) ÷ 5 = 25
- 100 + 2 × 25 = 150
8.A number line goes from 500 to 750 and is split into 10 equal spaces. The arrow is 9 spaces along from 500. What number does the arrow point to?
Answer: 725
- Each space is (750 − 500) ÷ 10 = 25
- 500 + 9 × 25 = 725
9.What number is halfway between 350 and 490?
Answer: 420
- 490 − 350 = 140; half of that is 70
- 350 + 70 = 420
10.A number line goes from 300 to 400 and is split into 5 equal spaces. The arrow is 3 spaces along from 300. What number does the arrow point to?
Answer: 360
- Each space is (400 − 300) ÷ 5 = 20
- 300 + 3 × 20 = 360
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.
