This resource is designed for demonstration of formal written methods for 2-digit vertical addition.

The calculation is shown in a horizontal format first as children frequently find it tricky to
transcribe one to the other.

The tricky columns tick box allows the random digits 1 to 9. This means that there are sometimes no tricky columns!

If you're working from home why not allow the children to set their own questions using this resource on a tablet.
