High Quality Content by WIKIPEDIA articles! The grid method is a form of long multiplication using a Partial Products Algorithm. The grid method differs in clearly breaking the multiplication and addition into two steps, and in being less dependent on place value. In recent years it has become very common in primary schools in England. While it is less efficient than the traditional method, it is considered to be more reliable, in that children are less likely to make mistakes. Since anyone doing a lot of multiplication would use a pocket calculator, efficiency is less important nowadays; equally, since this means most children will use the multiplication algorithm less often, a more explicit (hence memorable) method is useful.
