First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 20 to 25 and is split into 5 equal spaces. The arrow is 1 space along from 20. What number does the arrow point to?
Answer: 21
- Each space is (25 − 20) ÷ 5 = 1
- 20 + 1 × 1 = 21
2.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
3.A number line goes from 300 to 400 and is split into 10 equal spaces. The arrow is 4 spaces along from 300. What number does the arrow point to?
Answer: 340
- Each space is (400 − 300) ÷ 10 = 10
- 300 + 4 × 10 = 340
4.A number line goes from 400 to 500 and is split into 10 equal spaces. The arrow is 1 space along from 400. What number does the arrow point to?
Answer: 410
- Each space is (500 − 400) ÷ 10 = 10
- 400 + 1 × 10 = 410
5.A number line goes from 30 to 55 and is split into 5 equal spaces. The arrow is 3 spaces along from 30. What number does the arrow point to?
Answer: 45
- Each space is (55 − 30) ÷ 5 = 5
- 30 + 3 × 5 = 45
6.A number line goes from 90 to 115 and is split into 5 equal spaces. The arrow is 4 spaces along from 90. What number does the arrow point to?
Answer: 110
- Each space is (115 − 90) ÷ 5 = 5
- 90 + 4 × 5 = 110
7.A number line goes from 40 to 60 and is split into 10 equal spaces. The arrow is 9 spaces along from 40. What number does the arrow point to?
Answer: 58
- Each space is (60 − 40) ÷ 10 = 2
- 40 + 9 × 2 = 58
8.A number line goes from 60 to 70 and is split into 10 equal spaces. The arrow is 2 spaces along from 60. What number does the arrow point to?
Answer: 62
- Each space is (70 − 60) ÷ 10 = 1
- 60 + 2 × 1 = 62
9.A number line goes from 30 to 80 and is split into 10 equal spaces. The arrow is 3 spaces along from 30. What number does the arrow point to?
Answer: 45
- Each space is (80 − 30) ÷ 10 = 5
- 30 + 3 × 5 = 45
10.A number line goes from 800 to 900 and is split into 10 equal spaces. The arrow is 3 spaces along from 800. What number does the arrow point to?
Answer: 830
- Each space is (900 − 800) ÷ 10 = 10
- 800 + 3 × 10 = 830
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.
