The grid method is sometimes taught to students learning multiplication skills. It is an alternative to the long multiplication method that also uses a pencil and paper rather than a calculator.SignificanceThis method has been used mainly for its emphasis on breaking numbers down into more manageable units: hundreds, tens and ones. This is similar to the concept of “places” commonly used in simple math but the application is different.ConceptThe grid method is based on the concept of an array of counters, or dots arranged in a grid. If you divide the grid into quadrants we can determine the total number of dots by calculating the number of dots in each quadrant by multiplying the sides, and then adding the results together.FunctionThe grid method illustrates the idea of the array of counters, but you don’t have to draw out the rows of dots, you just use a grid of rectangles to represent the quadrants.Example ProblemSay you want to solve the problem 452 X 7. Draw a grid that has four bo
