Level 1 · Warm-up
1 Labels on a scale are 0, 50 and 100, with 5 small gaps between each pair. What is one small gap worth?
Show worked solution
10.
2 A scale has labels 20 apart with 4 gaps between each pair. Write the value of one gap, and the reading 2 gaps above 20.
Show worked solution
One gap is 5, so 2 gaps above 20 is 30.
3 A pointer sits halfway between the 40 and 50 marks. What does it read?
Show worked solution
45.
Level 2 · Core
4 How much water is in this jug? It is labelled every 100 mL with a mark every 50 mL.
Show worked solution
250 mL.
5 A scale is labelled every 50 with a mark every 10. Write the value of one mark, and the reading 3 marks above 100.
Show worked solution
One mark is 10, so 3 marks above 100 is 130.
6 A scale has gaps of 50. A pointer sits halfway between the 100 and 150 marks. What does it read?
Show worked solution
125.
Level 3 · Challenge
7 A scale is labelled 0, 20, 40 with 4 small gaps between each pair of labels, and an arrow points 1 gap below 40.1 One gap is worth 5.
2 The arrow reads 35.
3 The arrow reads 39.
Which statements are correct?
2 The arrow reads 35.
3 The arrow reads 39.
Which statements are correct?
Show worked solution
One gap is 20 ÷ 4 = 5 (1 ✓), so the arrow reads 40 − 5 = 35 (2 ✓, 3 ✗). 1 and 2.
8 A dial is labelled every 20 with a mark every 10, and the pointer sits halfway between the 60 and 70 marks. Write the value of one mark, and the reading.
Show worked solution
One mark is 10, and halfway between 60 and 70 is 65.
9 A scale is labelled 0, 100, 200 with 4 small gaps between each pair. What is one small gap worth?
