This primer is intended for preschool children and can become the first educational and developmental aid not only for tomorrow's first-graders, but also for those who are not yet going to school. Each letter in the primer corresponds to the color in whose name it appears first. In addition to the already known seven colors of the rainbow, children will become familiar with some of the components found in everyday life. Color associations and a poetic form of presentation, where each letter is a kind of fairy-tale character, will make the child’s first learning process more interesting, less tiring, and will help to better remember what has been learned. Enjoy your activities with your child! The author expresses his heartfelt gratitude to his beloved grandson, Roman Popov, for his active participation in creating illustrations for the primer.
