First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 500 to 1,000 and is split into 5 equal spaces. The arrow is 2 spaces along from 500. What number does the arrow point to?
Answer: 700
- Each space is (1,000 − 500) ÷ 5 = 100
- 500 + 2 × 100 = 700
2.A number line goes from 0 to 80 and is split into 4 equal spaces. The arrow is 1 space along from 0. What number does the arrow point to?
Answer: 20
- Each space is (80 − 0) ÷ 4 = 20
- 0 + 1 × 20 = 20
3.What number is halfway between 210 and 290?
Answer: 250
- 290 − 210 = 80; half of that is 40
- 210 + 40 = 250
4.A number line goes from 3,000 to 4,000 and is split into 4 equal spaces. The arrow is 1 space along from 3,000. What number does the arrow point to?
Answer: 3,250
- Each space is (4,000 − 3,000) ÷ 4 = 250
- 3,000 + 1 × 250 = 3,250
5.A number line goes from 200 to 325 and is split into 5 equal spaces. The arrow is 3 spaces along from 200. What number does the arrow point to?
Answer: 275
- Each space is (325 − 200) ÷ 5 = 25
- 200 + 3 × 25 = 275
6.What number is halfway between 120 and 600?
Answer: 360
- 600 − 120 = 480; half of that is 240
- 120 + 240 = 360
7.A number line goes from 900 to 1,100 and is split into 4 equal spaces. The arrow is 1 space along from 900. What number does the arrow point to?
Answer: 950
- Each space is (1,100 − 900) ÷ 4 = 50
- 900 + 1 × 50 = 950
8.A number line goes from 200 to 400 and is split into 10 equal spaces. The arrow is 3 spaces along from 200. What number does the arrow point to?
Answer: 260
- Each space is (400 − 200) ÷ 10 = 20
- 200 + 3 × 20 = 260
9.What number is halfway between 100 and 540?
Answer: 320
- 540 − 100 = 440; half of that is 220
- 100 + 220 = 320
10.A number line goes from 0 to 125 and is split into 5 equal spaces. The arrow is 2 spaces along from 0. What number does the arrow point to?
Answer: 50
- Each space is (125 − 0) ÷ 5 = 25
- 0 + 2 × 25 = 50
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.
