Mathematics. Ciphers for first graders. Practice of mental arithmetic skills

The manual presents game tasks in mathematics for working out computational skills. The child plunges into an exciting story, where he fights with evil and becomes a real hero! On each page he is waiting for tests in the form of mathematical encryptions, and at the end - the winner’s diploma. You, dear adults, are also waiting for a reward: the child will take possession of the skill of adding and subtracting numbers within 20, therefore, in the future, studying mathematics for him will be easier and faster.
Manual:
compiled on the basis of the principle of "play and study",
performs the function of a mathematical simulator, while protecting the child from mechanical monotony,
includes tasks with interdisciplinary connections: mathematics - " Man and the world ", mathematics - literary reading.
