SECOND PART OF BRAILLER ÁBACO

Photo taken from the book.

Reviewing the methods that exist, we elaborate this booklet that is aimed at support teachers and regular teachers as well as people who want to support the process of training and learning of all blind and visually impaired children, they want to show everyone the procedure that is followed in the abacus to make the operations differences.

The exercises are developed from right to left and the procedure is similar to that of ink, since the teacher has taught us that it is the same for all children, which has led us to modify the execution of these exercises to be similar to what the teacher is developing in the classroom. This does not mean that if you do it from left to right, you are doing it wrong. What is important in the case of the blind child is that she understands the steps that the math teacher follows when he is doing an exercise and that he builds and develop your own schemes.

The presentation of the first primer contains addition, subtraction, multiplication and division with natural numbers and their respective mathematical symbology; In the second book will work addition, subtraction, multiplication and division with decimal numbers and their respective mathematical symbology, the third book will work topics such as empowerment, maximum common divisor, least common multiple, addition, subtraction and finalization, the important thing is to support all those children with visual disabilities and blind to make this world easier for all of them I hope you like this nice information.
