A color-coded method of teaching basic arithmetic concepts and procedures
The method that is explained below was developed by the author in an effort to aid a fifth-grade boy who was severely retarded in arithmetic achievement. All conventional methods of explaining place value, such as the abacus, pocket charts, Cuisenaire rods, etc., were too abstract for this child, and the use of the materials had not led to his developing understanding of concepts.
