Aprašymas

Children with learning disabilities, slow learners, and even those with average intelligence find arithmetic tasks so difficult that they often avoid the subject. This book contains eleven chapters, presenting concepts on one to one correspondence, seriation, computational process, techniques in number counting, place value, money, calendar and time, fraction and multiplication. These facts have been systematically presented with the techniques and materials for solving each one. They have been presented from simple to complex, from the known to the unknown using concrete materials rather than theoretical presentations. This resource is for the grasp of teachers and learners in both conventional and special settings.
