How to memorize the multiplication table, or A walk with a key in the field of hundreds

As it is known, the best rest is a change of activities. Mathematics can also be both a serious matter and a relaxation at the same time. L.K. Filyakina's book is aimed at serving not as entertainment, but rather as an introduction to mathematics. In each section of the book, you can not only do calculations, but also play while doing so - with two people, three people, or in teams: an adult starts the game, and the children join in. Lydia Filyakina called her approach to the matter 'Intuitive-Imaginative Revival in Education'. She suggests that fathers and mothers, grandmothers and grandfathers, and of course, teachers, return to mathematics together with their children, grandchildren, and students - and return in a way that brings pleasure from solving puzzles, a smile, and the joy of success to everyone. The tasks in this book lead from the first encounters with numbers to further exploration of mathematics, aiming to make these encounters memorable, bright, and clever. 4th edition.
