First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 0 to 250 and is split into 10 equal spaces. The arrow is 1 space along from 0. What number does the arrow point to?
Answer: 25
- Each space is (250 − 0) ÷ 10 = 25
- 0 + 1 × 25 = 25
2.A number line goes from 800 to 1,200 and is split into 4 equal spaces. The arrow is 2 spaces along from 800. What number does the arrow point to?
Answer: 1,000
- Each space is (1,200 − 800) ÷ 4 = 100
- 800 + 2 × 100 = 1,000
3.What number is halfway between 320 and 600?
Answer: 460
- 600 − 320 = 280; half of that is 140
- 320 + 140 = 460
4.A number line goes from 300 to 800 and is split into 5 equal spaces. The arrow is 4 spaces along from 300. What number does the arrow point to?
Answer: 700
- Each space is (800 − 300) ÷ 5 = 100
- 300 + 4 × 100 = 700
5.A number line goes from 300 to 800 and is split into 10 equal spaces. The arrow is 4 spaces along from 300. What number does the arrow point to?
Answer: 500
- Each space is (800 − 300) ÷ 10 = 50
- 300 + 4 × 50 = 500
6.What number is halfway between 350 and 690?
Answer: 520
- 690 − 350 = 340; half of that is 170
- 350 + 170 = 520
7.A number line goes from 1,000 to 3,500 and is split into 10 equal spaces. The arrow is 5 spaces along from 1,000. What number does the arrow point to?
Answer: 2,250
- Each space is (3,500 − 1,000) ÷ 10 = 250
- 1,000 + 5 × 250 = 2,250
8.A number line goes from 300 to 800 and is split into 5 equal spaces. The arrow is 2 spaces along from 300. What number does the arrow point to?
Answer: 500
- Each space is (800 − 300) ÷ 5 = 100
- 300 + 2 × 100 = 500
9.What number is halfway between 360 and 760?
Answer: 560
- 760 − 360 = 400; half of that is 200
- 360 + 200 = 560
10.A number line goes from 600 to 1,000 and is split into 4 equal spaces. The arrow is 2 spaces along from 600. What number does the arrow point to?
Answer: 800
- Each space is (1,000 − 600) ÷ 4 = 100
- 600 + 2 × 100 = 800
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.
