In the 2nd part, work is carried out to systematize the knowledge of students about the quantities and their measures (measures of value, length, time), as well as the differentiation of numbers obtained under the count and during measurement. Acquaintance with such concepts as “ball”, “circle” is continued, the concepts of “circle”, “center”, “radius of the circle” and “radius of the circle” are introduced. The system of tasks is aimed not only at the mastery of children's mathematical knowledge and skills, but also to the correction of their psychophysical development.
