Answer to Question 1 (4 marks)
1. Negative numbers come before 0. The further a negative number is from zero, the smaller it is, so −9 is smallest. Order: −9, −4, −1, 0, 3, 6 (2 marks: 1 for the negatives in the right order, 1 for the full list).
2. The negative numbers are −9, −4 and −1. The largest is the one closest to zero: −1 (1 mark).
3. On a number line −5 is to the right of −8, so it is greater: −5 > −8 (1 mark). It is 5 degrees below freezing compared with 8 below, which is warmer.
Answer to Question 2 (4 marks)
1. Count back 5 to reach 0, then 3 more below zero: 5 − 8 = −3 (1 mark).
2. Count up 6 from −6 to reach 0, then 3 more: −6 + 9 = 3 (1 mark).
3. Each number is 3 less than the one before, so keep taking away 3: −3 − 3 = −6, then −6 − 3 = −9 (2 marks: 1 for each number).
Answer to Question 3 (4 marks)
1. The liquid stops 3 marks below the 0 line, so the thermometer shows −3 °C (1 mark).
2. Falling by 5 degrees means counting down 5 from −3: −4, −5, −6, −7, −8. The temperature is −8 °C (1 mark).
3. Freezing is 0 °C. −8 °C is 8 steps below zero, so it is 8 degrees below freezing (1 mark).
4. From −3 up to 0 is 3 degrees, and from 0 up to 4 is 4 degrees. The difference is 3 + 4 = 7 degrees (1 mark).
Answer to Question 4 (4 marks)
1. The coldest temperature is the lowest number. −12 is further below zero than −8, so Moscow (−12 °C) was coldest (1 mark).
2. Count up from Oslo's −8 °C to 0: 8 degrees. Then from 0 up to London's 3 °C: 3 degrees. The difference is 8 + 3 = 11 degrees (2 marks: 1 for crossing zero, 1 for 11).
3. Count down 6 from 3 °C: 3 to 0, then 3 more below zero. 3 − 6 = −3 °C (1 mark).
Answer to Question 5 (4 marks)
1. Count up 5 from −4: 4 steps take it to 0, then 1 more. At 10 am it is 1 °C (1 mark).
2. It rises 3 more: 1 + 3 = 4 °C at 2 pm (1 mark).
3. It falls by 7: 4 down to 0 is 4 steps, then 3 more below zero. At 10 pm it is −3 °C (1 mark).
4. The day's temperatures were −4, 1, 4 and −3 °C. Warmest 4 °C, coldest −4 °C. From −4 to 0 is 4 and from 0 to 4 is 4, so the difference is 8 degrees (1 mark).

How to use these Year 4 negative numbers test answers

First, sit the test under timed conditions before you read anything here. Then mark each answer and give yourself the marks shown, including method marks. When you lose marks, read the worked solution and find the step you missed. After that, revise the negative numbers lesson and redo the worksheet.

Also, the Year 4 negative numbers test answers are available as a PDF, so a teacher can mark printed tests quickly. Moreover, all the pages of this chapter work together, so you can move between them at any time. For example, many pupils read the lesson on Monday, practise on Wednesday and test themselves on Friday.
