First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 800 to 1,200 and is split into 4 equal spaces. The arrow is 3 spaces along from 800. What number does the arrow point to?
Answer: 1,100
- Each space is (1,200 − 800) ÷ 4 = 100
- 800 + 3 × 100 = 1,100
2.A number line goes from 900 to 1,150 and is split into 10 equal spaces. The arrow is 4 spaces along from 900. What number does the arrow point to?
Answer: 1,000
- Each space is (1,150 − 900) ÷ 10 = 25
- 900 + 4 × 25 = 1,000
3.What number is halfway between 80 and 140?
Answer: 110
- 140 − 80 = 60; half of that is 30
- 80 + 30 = 110
4.A number line goes from 8,000 to 9,000 and is split into 4 equal spaces. The arrow is 1 space along from 8,000. What number does the arrow point to?
Answer: 8,250
- Each space is (9,000 − 8,000) ÷ 4 = 250
- 8,000 + 1 × 250 = 8,250
5.A number line goes from 400 to 500 and is split into 5 equal spaces. The arrow is 4 spaces along from 400. What number does the arrow point to?
Answer: 480
- Each space is (500 − 400) ÷ 5 = 20
- 400 + 4 × 20 = 480
6.What number is halfway between 120 and 560?
Answer: 340
- 560 − 120 = 440; half of that is 220
- 120 + 220 = 340
7.A number line goes from 9,000 to 10,000 and is split into 4 equal spaces. The arrow is 1 space along from 9,000. What number does the arrow point to?
Answer: 9,250
- Each space is (10,000 − 9,000) ÷ 4 = 250
- 9,000 + 1 × 250 = 9,250
8.A number line goes from 500 to 750 and is split into 10 equal spaces. The arrow is 3 spaces along from 500. What number does the arrow point to?
Answer: 575
- Each space is (750 − 500) ÷ 10 = 25
- 500 + 3 × 25 = 575
9.What number is halfway between 170 and 530?
Answer: 350
- 530 − 170 = 360; half of that is 180
- 170 + 180 = 350
10.A number line goes from 800 to 1,050 and is split into 5 equal spaces. The arrow is 3 spaces along from 800. What number does the arrow point to?
Answer: 950
- Each space is (1,050 − 800) ÷ 5 = 50
- 800 + 3 × 50 = 950
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.
Great work. Here's what to try next:
