Here we have two pages which give a series of questions related to the six digits shown. Some of these might take longer than others; for example, finding three numbers from six that total 20 will probably involve some 'trial and improvement' techniques, although children who are confident with knowing the totals of any 2 single digit numbers will find this easier. This is a good page to use to give a little extra addition and subtraction practice as well as reinforcing the vocabulary such as 'smallest', 'largest', 'total', 'odd' and 'even'.
