First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 400 to 500 and is split into 10 equal spaces. The arrow is 9 spaces along from 400. What number does the arrow point to?
Answer: 490
- Each space is (500 − 400) ÷ 10 = 10
- 400 + 9 × 10 = 490
2.A number line goes from 0 to 50 and is split into 10 equal spaces. The arrow is 9 spaces along from 0. What number does the arrow point to?
Answer: 45
- Each space is (50 − 0) ÷ 10 = 5
- 0 + 9 × 5 = 45
3.A number line goes from 70 to 120 and is split into 10 equal spaces. The arrow is 7 spaces along from 70. What number does the arrow point to?
Answer: 105
- Each space is (120 − 70) ÷ 10 = 5
- 70 + 7 × 5 = 105
4.A number line goes from 80 to 130 and is split into 10 equal spaces. The arrow is 7 spaces along from 80. What number does the arrow point to?
Answer: 115
- Each space is (130 − 80) ÷ 10 = 5
- 80 + 7 × 5 = 115
5.A number line goes from 70 to 75 and is split into 5 equal spaces. The arrow is 4 spaces along from 70. What number does the arrow point to?
Answer: 74
- Each space is (75 − 70) ÷ 5 = 1
- 70 + 4 × 1 = 74
6.A number line goes from 60 to 65 and is split into 5 equal spaces. The arrow is 3 spaces along from 60. What number does the arrow point to?
Answer: 63
- Each space is (65 − 60) ÷ 5 = 1
- 60 + 3 × 1 = 63
7.A number line goes from 0 to 100 and is split into 10 equal spaces. The arrow is 4 spaces along from 0. What number does the arrow point to?
Answer: 40
- Each space is (100 − 0) ÷ 10 = 10
- 0 + 4 × 10 = 40
8.A number line goes from 300 to 350 and is split into 5 equal spaces. The arrow is 3 spaces along from 300. What number does the arrow point to?
Answer: 330
- Each space is (350 − 300) ÷ 5 = 10
- 300 + 3 × 10 = 330
9.A number line goes from 900 to 1,000 and is split into 10 equal spaces. The arrow is 5 spaces along from 900. What number does the arrow point to?
Answer: 950
- Each space is (1,000 − 900) ÷ 10 = 10
- 900 + 5 × 10 = 950
10.A number line goes from 80 to 85 and is split into 5 equal spaces. The arrow is 2 spaces along from 80. What number does the arrow point to?
Answer: 82
- Each space is (85 − 80) ÷ 5 = 1
- 80 + 2 × 1 = 82
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.
