Addition and Subtraction: 1000 Examples and Mathematical Encodings

This collection of mathematical tasks will help elementary school teachers, as well as after-school group educators, extracurricular and out-of-school activity organizers, and parents of younger schoolchildren to engage children in mastering and consolidating specific sections of the mathematics curriculum. The manual includes a variety of non-standard tasks (mathematical encodings, numerical puzzles, a multitude of examples and problems), the solutions of which will contribute to the development and consolidation of computational skills up to 100 for elementary school students, the development of intelligence, logic, and thinking in general.
