The predecessors of the “Preschool Gymnasium” program were the author’s books, published in the “Raising a Child” series from 2 years of age to school, which contained a detailed lesson plan for every day. The result of this work was a program that completes the child’s preparation for school life. The exciting tasks recommended for children of senior preschool age and the gradual complication of the proposed material allow them to successfully prepare them for school. The program will help educators work on teaching literacy, reading skills, and basic math knowledge. The “Preschool Gymnasium” program meets Federal state requirements in the field of preschool education. The program is intended for teachers of preschool educational institutions and preparatory classes in schools, as well as tutors and parents of children of senior preschool age.
