The checkered board was developed by the famous children educator Maria Montessori, who spent her life developing methods, which motivate children to learn in an effective way.
Give multiplication exercises to children and they will be able to solve them in a comprehensive and easy way thanks to this board.
Children can use the board from the early stage of learning mathematics (some start even at kindergarten).
Children can use this board to help them carrying out multiplication of numbers with paper and pen, as most of adults do when a calculator is not available.
