Maths Support Week 2 Summer 2

Next week, the children will be consolidating on addition and subtraction using columnar addition and subtraction.

Addition

Writing it down

When writing down sums, separate the numbers into units, tens, hundreds and thousands. List the numbers in a column and always start adding with the units first.

So when adding together 7948 + 1223, you should write it down like this:

addiing the sum 7948 + 1223

Some tips for addition

  • Estimate first and check afterwards – it’s a good idea to estimate a rough answer first and then check your actual answer.
  • Order doesn’t matter – remember that in addition 394 + 88 is the same as 88 + 394.

Subtraction

Writing it down

If the numbers are too high or too difficult to subtract in your head, write them down in columns. Always start subtracting with the units first.

Subtractio: 6418 - 1223 = 5195
