Addition (partitioning or column methods)






Subtraction (bridging the gap or column methods)

            e.g. 628-235 or £6.28 - £2.35 children need to:

  • draw an empty number line
  • write the numbers at either end
  • calculate the jump to the next hundred/whole pound
  • calculate the jump to the largest number
  • add the jumps together
