This addition and subtraction of children is taught to perform oral computing techniques (the example is recorded in a line). Much attention is paid to the tabular multiplication of numbers 2, 3, 4, 5 (all cases) and division by 2, 3, 4, 5. The system of tasks contributes to the achievement of personal and subject results of training, the correction of the psychophysical development of students.
