First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 300 to 500 and is split into 4 equal spaces. The arrow is 1 space along from 300. What number does the arrow point to?
Answer: 350
- Each space is (500 − 300) ÷ 4 = 50
- 300 + 1 × 50 = 350
2.A number line goes from 900 to 1,150 and is split into 5 equal spaces. The arrow is 4 spaces along from 900. What number does the arrow point to?
Answer: 1,100
- Each space is (1,150 − 900) ÷ 5 = 50
- 900 + 4 × 50 = 1,100
3.What number is halfway between 260 and 600?
Answer: 430
- 600 − 260 = 340; half of that is 170
- 260 + 170 = 430
4.A number line goes from 300 to 400 and is split into 4 equal spaces. The arrow is 1 space along from 300. What number does the arrow point to?
Answer: 325
- Each space is (400 − 300) ÷ 4 = 25
- 300 + 1 × 25 = 325
5.A number line goes from 400 to 650 and is split into 5 equal spaces. The arrow is 1 space along from 400. What number does the arrow point to?
Answer: 450
- Each space is (650 − 400) ÷ 5 = 50
- 400 + 1 × 50 = 450
6.What number is halfway between 210 and 430?
Answer: 320
- 430 − 210 = 220; half of that is 110
- 210 + 110 = 320
7.A number line goes from 500 to 600 and is split into 4 equal spaces. The arrow is 1 space along from 500. What number does the arrow point to?
Answer: 525
- Each space is (600 − 500) ÷ 4 = 25
- 500 + 1 × 25 = 525
8.A number line goes from 0 to 100 and is split into 4 equal spaces. The arrow is 3 spaces along from 0. What number does the arrow point to?
Answer: 75
- Each space is (100 − 0) ÷ 4 = 25
- 0 + 3 × 25 = 75
9.What number is halfway between 40 and 120?
Answer: 80
- 120 − 40 = 80; half of that is 40
- 40 + 40 = 80
10.A number line goes from 300 to 380 and is split into 4 equal spaces. The arrow is 1 space along from 300. What number does the arrow point to?
Answer: 320
- Each space is (380 − 300) ÷ 4 = 20
- 300 + 1 × 20 = 320
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.
