Key Topics to Revise

1

1. Making sums equal

  • Two groups of numbers can sometimes be balanced by interchanging a pair of numbers.
  • The aim is to make the sums of both groups equal using the least number of moves.
  • A careful trial of different pairs helps find the best swap.

2. Fuel arithmetic and place value addition

  • Different vehicles need different quantities of fuel: motorbikes use 5 to 15 litres, cars 15 to 50 litres, lorries and trucks 150 to 500 litres, and a train 5,000 litres.
  • Fuel should be saved because it is limited.
  • Reducing fuel use also helps cut pollution.

3. Relationship between addition and subtraction

  • Addition and subtraction are related operations.
  • If 46 + 21 = 67, then 67 - 21 = 46 and 67 - 46 = 21.
  • If 198 - 98 = 100, then 100 + 98 = 198 and 198 - 100 = 98.

4. Consecutive numbers and their sums

  • Numbers that follow one another in order without skipping any number are called consecutive numbers.
  • Examples include 1, 2, 3, 4, 5 and 29, 30, 31, 32.
  • The sum of consecutive numbers shows patterns.
