First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 900 to 1,400 and is split into 10 equal spaces. The arrow is 2 spaces along from 900. What number does the arrow point to?
Answer: 1,000
- Each space is (1,400 − 900) ÷ 10 = 50
- 900 + 2 × 50 = 1,000
2.A number line goes from 500 to 1,000 and is split into 5 equal spaces. The arrow is 1 space along from 500. What number does the arrow point to?
Answer: 600
- Each space is (1,000 − 500) ÷ 5 = 100
- 500 + 1 × 100 = 600
3.What number is halfway between 90 and 430?
Answer: 260
- 430 − 90 = 340; half of that is 170
- 90 + 170 = 260
4.A number line goes from 0 to 500 and is split into 10 equal spaces. The arrow is 4 spaces along from 0. What number does the arrow point to?
Answer: 200
- Each space is (500 − 0) ÷ 10 = 50
- 0 + 4 × 50 = 200
5.A number line goes from 600 to 850 and is split into 5 equal spaces. The arrow is 3 spaces along from 600. What number does the arrow point to?
Answer: 750
- Each space is (850 − 600) ÷ 5 = 50
- 600 + 3 × 50 = 750
6.What number is halfway between 260 and 860?
Answer: 560
- 860 − 260 = 600; half of that is 300
- 260 + 300 = 560
7.A number line goes from 600 to 800 and is split into 4 equal spaces. The arrow is 2 spaces along from 600. What number does the arrow point to?
Answer: 700
- Each space is (800 − 600) ÷ 4 = 50
- 600 + 2 × 50 = 700
8.A number line goes from 4,000 to 5,250 and is split into 5 equal spaces. The arrow is 4 spaces along from 4,000. What number does the arrow point to?
Answer: 5,000
- Each space is (5,250 − 4,000) ÷ 5 = 250
- 4,000 + 4 × 250 = 5,000
9.What number is halfway between 320 and 600?
Answer: 460
- 600 − 320 = 280; half of that is 140
- 320 + 140 = 460
10.A number line goes from 200 to 300 and is split into 5 equal spaces. The arrow is 4 spaces along from 200. What number does the arrow point to?
Answer: 280
- Each space is (300 − 200) ÷ 5 = 20
- 200 + 4 × 20 = 280
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.
