First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 800 to 880 and is split into 4 equal spaces. The arrow is 2 spaces along from 800. What number does the arrow point to?
Answer: 840
- Each space is (880 − 800) ÷ 4 = 20
- 800 + 2 × 20 = 840
2.A number line goes from 400 to 600 and is split into 4 equal spaces. The arrow is 1 space along from 400. What number does the arrow point to?
Answer: 450
- Each space is (600 − 400) ÷ 4 = 50
- 400 + 1 × 50 = 450
3.What number is halfway between 280 and 800?
Answer: 540
- 800 − 280 = 520; half of that is 260
- 280 + 260 = 540
4.A number line goes from 500 to 700 and is split into 4 equal spaces. The arrow is 1 space along from 500. What number does the arrow point to?
Answer: 550
- Each space is (700 − 500) ÷ 4 = 50
- 500 + 1 × 50 = 550
5.A number line goes from 300 to 380 and is split into 4 equal spaces. The arrow is 1 space along from 300. What number does the arrow point to?
Answer: 320
- Each space is (380 − 300) ÷ 4 = 20
- 300 + 1 × 20 = 320
6.What number is halfway between 320 and 780?
Answer: 550
- 780 − 320 = 460; half of that is 230
- 320 + 230 = 550
7.A number line goes from 300 to 400 and is split into 5 equal spaces. The arrow is 1 space along from 300. What number does the arrow point to?
Answer: 320
- Each space is (400 − 300) ÷ 5 = 20
- 300 + 1 × 20 = 320
8.A number line goes from 900 to 1,150 and is split into 5 equal spaces. The arrow is 3 spaces along from 900. What number does the arrow point to?
Answer: 1,050
- Each space is (1,150 − 900) ÷ 5 = 50
- 900 + 3 × 50 = 1,050
9.What number is halfway between 400 and 720?
Answer: 560
- 720 − 400 = 320; half of that is 160
- 400 + 160 = 560
10.A number line goes from 0 to 100 and is split into 5 equal spaces. The arrow is 4 spaces along from 0. What number does the arrow point to?
Answer: 80
- Each space is (100 − 0) ÷ 5 = 20
- 0 + 4 × 20 = 80
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.
