As well as putting the larger number first, the smaller
number is partitioned into tens and units.
86 + 57 =
86 + 50 + 7 = 86 + 10 + 10 +10 + 10 + 10 + 7 = 143
Or they may partition the 7 down to 4 + 3 to get to the
nearest 10.

When children start to consider adding numbers vertically
‘Hundred, tens and ones’ can be used. They will then go on
to understand that 10 ones can be exchanged for one ten).
Children will add the Units and then the Tens.

Diennes should be used to support this method.

If the ones add up to 10 or more, you exchange 10 ones for
a ten.
