First find how much each space is worth: (end − start) ÷ number of spaces.
1.A number line goes from 700 to 1,700 and is split into 10 equal spaces. The arrow is 2 spaces along from 700. What number does the arrow point to?
Answer: 900
- Each space is (1,700 − 700) ÷ 10 = 100
- 700 + 2 × 100 = 900
2.A number line goes from 800 to 1,300 and is split into 5 equal spaces. The arrow is 3 spaces along from 800. What number does the arrow point to?
Answer: 1,100
- Each space is (1,300 − 800) ÷ 5 = 100
- 800 + 3 × 100 = 1,100
3.What number is halfway between 360 and 840?
Answer: 600
- 840 − 360 = 480; half of that is 240
- 360 + 240 = 600
4.A number line goes from 600 to 725 and is split into 5 equal spaces. The arrow is 4 spaces along from 600. What number does the arrow point to?
Answer: 700
- Each space is (725 − 600) ÷ 5 = 25
- 600 + 4 × 25 = 700
5.A number line goes from 400 to 900 and is split into 5 equal spaces. The arrow is 4 spaces along from 400. What number does the arrow point to?
Answer: 800
- Each space is (900 − 400) ÷ 5 = 100
- 400 + 4 × 100 = 800
6.What number is halfway between 160 and 440?
Answer: 300
- 440 − 160 = 280; half of that is 140
- 160 + 140 = 300
7.A number line goes from 100 to 200 and is split into 5 equal spaces. The arrow is 4 spaces along from 100. What number does the arrow point to?
Answer: 180
- Each space is (200 − 100) ÷ 5 = 20
- 100 + 4 × 20 = 180
8.A number line goes from 0 to 500 and is split into 5 equal spaces. The arrow is 4 spaces along from 0. What number does the arrow point to?
Answer: 400
- Each space is (500 − 0) ÷ 5 = 100
- 0 + 4 × 100 = 400
9.What number is halfway between 10 and 190?
Answer: 100
- 190 − 10 = 180; half of that is 90
- 10 + 90 = 100
10.A number line goes from 400 to 650 and is split into 10 equal spaces. The arrow is 5 spaces along from 400. What number does the arrow point to?
Answer: 525
- Each space is (650 − 400) ÷ 10 = 25
- 400 + 5 × 25 = 525
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.
