Assumptions To Watch Out For

  • Do not assume that your children know to read “+” as plus or add. Similarly ensure they are confident in their understanding of the minus (“ - “) symbol.
  • Do not assume that because your children can solve 7 + 8 = in the horizontal format, they automatically can solve the same addition when it is formatted vertically.
  • Do not assume that your children find adding or subtracting zero as being obvious. This is especially true for those who have experience with multiplication where the operation with zero results in an answer of zero.
