Exercise books are an ideal helper when repeating primary school material during the holidays. Thus, during regular practice, children will not lose the knowledge and ability to concentrate that they have painstakingly acquired during the past school year, and the return to school in September will be much easier for them. Each double page contains exercises in the Czech language, mathematics, but also elementary lessons. The tasks are short and clearly graphically processed and are based on the primary school curriculum. The curriculum is also practiced in the form of playful tasks that amuse the children and thus motivate them to solve other exercises.
