First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 5.2 to 5.45 and is split into 5 equal spaces. The arrow is 3 spaces along from 5.2. What number does the arrow point to?
Answer: 5.35
- Each space is (5.45 − 5.2) ÷ 5 = 0.05
- 5.2 + 3 × 0.05 = 5.35
2.A number line goes from 5 to 7 and is split into 10 equal spaces. The arrow is 4 spaces along from 5. What number does the arrow point to?
Answer: 5.8
- Each space is (7 − 5) ÷ 10 = 0.2
- 5 + 4 × 0.2 = 5.8
3.A number line goes from 1 to 2 and is split into 6 equal spaces. The arrow is 4 spaces along from 1. Write the number at the arrow as a fraction or mixed number.
Answer: 1
- Each space is
- 4 spaces = =
4.A number line goes from 3 to 5.5 and is split into 5 equal spaces. The arrow is 2 spaces along from 3. What number does the arrow point to?
Answer: 4
- Each space is (5.5 − 3) ÷ 5 = 0.5
- 3 + 2 × 0.5 = 4
5.A number line goes from 0.5 to 0.75 and is split into 5 equal spaces. The arrow is 4 spaces along from 0.5. What number does the arrow point to?
Answer: 0.7
- Each space is (0.75 − 0.5) ÷ 5 = 0.05
- 0.5 + 4 × 0.05 = 0.7
6.A number line goes from 1 to 2 and is split into 3 equal spaces. The arrow is 2 spaces along from 1. Write the number at the arrow as a fraction or mixed number.
Answer: 1
- Each space is
- 2 spaces =
7.A number line goes from 4.8 to 5.3 and is split into 10 equal spaces. The arrow is 5 spaces along from 4.8. What number does the arrow point to?
Answer: 5.05
- Each space is (5.3 − 4.8) ÷ 10 = 0.05
- 4.8 + 5 × 0.05 = 5.05
8.A number line goes from 8 to 10 and is split into 4 equal spaces. The arrow is 3 spaces along from 8. What number does the arrow point to?
Answer: 9.5
- Each space is (10 − 8) ÷ 4 = 0.5
- 8 + 3 × 0.5 = 9.5
9.A number line goes from 1 to 2 and is split into 5 equal spaces. The arrow is 2 spaces along from 1. Write the number at the arrow as a fraction or mixed number.
Answer: 1
- Each space is
- 2 spaces =
10.A number line goes from 5 to 6 and is split into 10 equal spaces. The arrow is 2 spaces along from 5. What number does the arrow point to?
Answer: 5.2
- Each space is (6 − 5) ÷ 10 = 0.1
- 5 + 2 × 0.1 = 5.2
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.
