First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 600 to 680 and is split into 4 equal spaces. The arrow is 2 spaces along from 600. What number does the arrow point to?
Answer: 640
- Each space is (680 − 600) ÷ 4 = 20
- 600 + 2 × 20 = 640
2.A number line goes from 7,000 to 8,000 and is split into 4 equal spaces. The arrow is 1 space along from 7,000. What number does the arrow point to?
Answer: 7,250
- Each space is (8,000 − 7,000) ÷ 4 = 250
- 7,000 + 1 × 250 = 7,250
3.What number is halfway between 210 and 350?
Answer: 280
- 350 − 210 = 140; half of that is 70
- 210 + 70 = 280
4.A number line goes from 700 to 1,700 and is split into 10 equal spaces. The arrow is 7 spaces along from 700. What number does the arrow point to?
Answer: 1,400
- Each space is (1,700 − 700) ÷ 10 = 100
- 700 + 7 × 100 = 1,400
5.A number line goes from 100 to 225 and is split into 5 equal spaces. The arrow is 1 space along from 100. What number does the arrow point to?
Answer: 125
- Each space is (225 − 100) ÷ 5 = 25
- 100 + 1 × 25 = 125
6.What number is halfway between 210 and 470?
Answer: 340
- 470 − 210 = 260; half of that is 130
- 210 + 130 = 340
7.A number line goes from 0 to 80 and is split into 4 equal spaces. The arrow is 3 spaces along from 0. What number does the arrow point to?
Answer: 60
- Each space is (80 − 0) ÷ 4 = 20
- 0 + 3 × 20 = 60
8.A number line goes from 0 to 200 and is split into 10 equal spaces. The arrow is 9 spaces along from 0. What number does the arrow point to?
Answer: 180
- Each space is (200 − 0) ÷ 10 = 20
- 0 + 9 × 20 = 180
9.What number is halfway between 290 and 890?
Answer: 590
- 890 − 290 = 600; half of that is 300
- 290 + 300 = 590
10.A number line goes from 0 to 500 and is split into 5 equal spaces. The arrow is 1 space along from 0. What number does the arrow point to?
Answer: 100
- Each space is (500 − 0) ÷ 5 = 100
- 0 + 1 × 100 = 100
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.
