On the face of it this might look like an easy page, but in fact many children find this quite tricky. It should not be tried until children have a good grasp of the standard written method of addition.The addition calculation has been laid out in the standard way, together with the answer. However, two of the digits in the sum are missing. Sometimes it is easy to find the missing digit, but not always, especially when tens have been ‘carried’ into hundreds.
If children get this page correct it shows a good understanding of the standard method of addition. If they struggle it would be well worth looking again at this method.
