The Primary Framework for Mathematics would suggest that adding two single digits should always be done ‘in your head’ as children are expected to know them. However, parents like to see some written confirmation, and many children love doing a page of written sums, so we will start with a two straight forward ‘adding 5 to a single digit’ worksheets. All answers are only up to 10.
With all these worksheets you may well come across two questions which are identical. Whilst this rarely happens in a text book I believe that constant practice and reinforcement is the key to learning number bonds and having the same question twice is a good idea.
