Asian students are famous for their mathematical prowess, and these are the books that they use to gain those skills. If you want your child to learn to think mathematically, not just be able to solve math problems, you will be pleased and surprised with how well your student progresses. The textbooks teach the concepts and the workbooks are designed to be done independently by your student, and are paperback, with happy, color illustrations-very kid friendly. We offer the U.S. edition (which has been minimally modified to teach American money and U.S. spellings). Test scores conclusively and repeatedly put Singapore Primary Mathematics in top rank in international tests! Singapore's genius is in a unique pattern of moving from hands-on demonstrations, to picture drawings (concrete examples with pictures) to the abstract (numbers and symbols) in a natural, easy-to-understand progression.
