First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 100 to 600 and is split into 5 equal spaces. The arrow is 2 spaces along from 100. What number does the arrow point to?
Answer: 300
- Each space is (600 − 100) ÷ 5 = 100
- 100 + 2 × 100 = 300
2.A number line goes from 400 to 480 and is split into 4 equal spaces. The arrow is 2 spaces along from 400. What number does the arrow point to?
Answer: 440
- Each space is (480 − 400) ÷ 4 = 20
- 400 + 2 × 20 = 440
3.What number is halfway between 30 and 290?
Answer: 160
- 290 − 30 = 260; half of that is 130
- 30 + 130 = 160
4.A number line goes from 300 to 800 and is split into 10 equal spaces. The arrow is 5 spaces along from 300. What number does the arrow point to?
Answer: 550
- Each space is (800 − 300) ÷ 10 = 50
- 300 + 5 × 50 = 550
5.A number line goes from 700 to 1,100 and is split into 4 equal spaces. The arrow is 1 space along from 700. What number does the arrow point to?
Answer: 800
- Each space is (1,100 − 700) ÷ 4 = 100
- 700 + 1 × 100 = 800
6.What number is halfway between 380 and 920?
Answer: 650
- 920 − 380 = 540; half of that is 270
- 380 + 270 = 650
7.A number line goes from 9,000 to 10,000 and is split into 4 equal spaces. The arrow is 2 spaces along from 9,000. What number does the arrow point to?
Answer: 9,500
- Each space is (10,000 − 9,000) ÷ 4 = 250
- 9,000 + 2 × 250 = 9,500
8.A number line goes from 200 to 600 and is split into 4 equal spaces. The arrow is 1 space along from 200. What number does the arrow point to?
Answer: 300
- Each space is (600 − 200) ÷ 4 = 100
- 200 + 1 × 100 = 300
9.What number is halfway between 300 and 680?
Answer: 490
- 680 − 300 = 380; half of that is 190
- 300 + 190 = 490
10.A number line goes from 900 to 1,000 and is split into 4 equal spaces. The arrow is 2 spaces along from 900. What number does the arrow point to?
Answer: 950
- Each space is (1,000 − 900) ÷ 4 = 25
- 900 + 2 × 25 = 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.
