Level of development of ability to determine regularities in children of six and seven years old
(RESUME)

On the example of fulfilling three exercises - two arithmetical, and one to identify meaningful peculiarities (form and color) - the levels of development of ability to determine regularities are compared in six-year-olds of a Zero Grade at school, and of a senior group at Kindergarten. The post-testing was arranged a year later. The instruction according to a specially designed curriculum in the Zero Grade has led to the much higher development of ability to determine regularities in six-year-olds at school.
