1. Answer to Question 1 (4 marks)

   1. 1 metre is 100 cm, so 3 m is 100 + 100 + 100 = 300 cm. (1 mark)
   2. 1 kg is 1000 g. Count the thousands in 2000: 1000, 2000. That is 2 kg. (1 mark)
   3. 500 litres would fill a huge tank, not a bottle. A bottle is small, so it holds 500 ml. (1 mark)
   4. 1 litre is 1000 ml, so 4 litres is 4 × 1000 = 4000 ml. (1 mark)

2. Answer to Question 2 (4 marks)

   1. 1 metre is the same as 100 centimetres, so Ella's ribbon is 100 cm long. (1 mark)
   2. Compare 100 cm and 85 cm. 100 is greater than 85, so Ella's ribbon is longer. (1 mark)
   3. Count on from 85 to 100: 5 to make 90, then 10 to make 100. 5 + 10 = 15 cm longer. (1 mark)
   4. Cut 30 cm from 85 cm: 85 − 30 = 55 cm. Only the tens digit changes, from 8 to 5. (1 mark)

3. Answer to Question 3 (4 marks)

   1. The bag is 1 kg, which is 1000 g. The cake uses 350 g: 1000 − 350 = 650 g of flour left. (1 mark)
   2. The jug has 600 ml and the recipe uses 250 ml: 600 − 250 = 350 ml of milk left. (1 mark)
   3. Each kilogram is 1000 grams. For 3 kg count in thousands: 1000, 2000, 3000. So 3 kg = 3000 g. (2 marks: 1 for using 1000 g in 1 kg, 1 for 3000)

4. Answer to Question 4 (4 marks)

   1. Find the difference between 12 °C and 7 °C: count on from 7 to 12, which is 5. Tuesday is 5 degrees warmer. (1 mark)
   2. Wednesday is 3 degrees colder than Tuesday's 12 °C: 12 − 3 = 9 °C. (1 mark)
   3. The temperatures are 7 °C, 12 °C and 9 °C. The highest is 12 °C, so Tuesday is the warmest day. (1 mark)
   4. 0 °C is the temperature at which water freezes. 7 is above 0 on the thermometer, so 7 °C is warmer. (1 mark)

5. Answer to Question 5 (4 marks)

   1. Each stone is 60 cm long and there are 4 of them: 60 + 60 + 60 + 60 = 240 cm. (1 mark)
   2. Each metre is 100 cm, so 3 metres is 300 cm. (1 mark)
   3. Count on from 240 to 300: 60 more. So 60 cm more is needed, which is exactly one more stone. (1 mark)
   4. Two cans of 5 litres hold 5 + 5 = 10 litres. Each litre is 1000 ml, so 10 litres is 10 000 ml. (1 mark)
