First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 800 to 900 and is split into 10 equal spaces. The arrow is 5 spaces along from 800. What number does the arrow point to?
Answer: 850
- Each space is (900 − 800) ÷ 10 = 10
- 800 + 5 × 10 = 850
2.A number line goes from 100 to 150 and is split into 5 equal spaces. The arrow is 2 spaces along from 100. What number does the arrow point to?
Answer: 120
- Each space is (150 − 100) ÷ 5 = 10
- 100 + 2 × 10 = 120
3.A number line goes from 300 to 400 and is split into 10 equal spaces. The arrow is 2 spaces along from 300. What number does the arrow point to?
Answer: 320
- Each space is (400 − 300) ÷ 10 = 10
- 300 + 2 × 10 = 320
4.A number line goes from 50 to 75 and is split into 5 equal spaces. The arrow is 2 spaces along from 50. What number does the arrow point to?
Answer: 60
- Each space is (75 − 50) ÷ 5 = 5
- 50 + 2 × 5 = 60
5.A number line goes from 60 to 65 and is split into 5 equal spaces. The arrow is 1 space along from 60. What number does the arrow point to?
Answer: 61
- Each space is (65 − 60) ÷ 5 = 1
- 60 + 1 × 1 = 61
6.A number line goes from 10 to 20 and is split into 10 equal spaces. The arrow is 5 spaces along from 10. What number does the arrow point to?
Answer: 15
- Each space is (20 − 10) ÷ 10 = 1
- 10 + 5 × 1 = 15
7.A number line goes from 20 to 30 and is split into 10 equal spaces. The arrow is 5 spaces along from 20. What number does the arrow point to?
Answer: 25
- Each space is (30 − 20) ÷ 10 = 1
- 20 + 5 × 1 = 25
8.A number line goes from 100 to 150 and is split into 5 equal spaces. The arrow is 4 spaces along from 100. What number does the arrow point to?
Answer: 140
- Each space is (150 − 100) ÷ 5 = 10
- 100 + 4 × 10 = 140
9.A number line goes from 70 to 80 and is split into 10 equal spaces. The arrow is 5 spaces along from 70. What number does the arrow point to?
Answer: 75
- Each space is (80 − 70) ÷ 10 = 1
- 70 + 5 × 1 = 75
10.A number line goes from 20 to 40 and is split into 10 equal spaces. The arrow is 8 spaces along from 20. What number does the arrow point to?
Answer: 36
- Each space is (40 − 20) ÷ 10 = 2
- 20 + 8 × 2 = 36
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.
