Taschenbuch. Condizione: Neu. Neuware - Traditional long division is very difficult for third and fourth-graders. They must estimate or guess quotient digits and then test these guesses with error-prone multiplication. Errors usually cannot be found until the long, frustrating process ends with a result that does not check. Good News Long Division requires no guessing and no multiplication. It is easily checked as it it is done to eliminate errors as they occur. Good News Multiplication is much easier than the traditional method because it involves absolutely no multiplication, so no memorization of multiplication tables is required. Good News multiplication and division become only slightly more difficulty as more digits are added to multipliers or divisors. By contrast, traditional methods become far more difficult as these operands get bigger. The only skills needed to learn these efficient new methods are those that third-graders already have: adding, subtracting, and comparing numbers. Furthermore, these new methods provide excellent insight into the real nature of multiplication and division. Good News Multiplication and Good News Long Division are much simpler, easier, and quicker to learn. Help your children learn the new and better way today.…
