![]() Draw a grid containing as many columns as the number of digits in the first number and as many rows as the number of digits in the second number.To do the grid method of multiplication, follow these steps: How to Do the Grid Method of Multiplication Whilst the grid method can be used as an alternative to the long multiplication method, an understanding of grid method multiplication is worthwhile in itself as the same concepts of multiplication can be applied to other mathematical topics such as area and algebra. This structure generally helps students to avoid mistakes as it breaks the multiplication down further and is easier to understand. ![]() The grid method is used to provide structure to multiplying larger numbers as an alternative to long multiplication. We can now use column addition to find the total of the row totals. Next, we add the numbers in the middle row of our grid.įinally, we add the numbers in the bottom row of our grid. We’ll begin by adding the numbers in the first row of our grid. We can add the numbers row by row and use column addition. Once all of the boxes in the grid are filled, these answers are added together to make a total. We write ‘12 000’ where their column and row meet. We multiply these two numbers together and write the answer in each box of the grid. One number is above the box and one number is to the left of the box. In the grid method, each box has two partitioned numbers next to it. The two numbers are partitioned into 200 + 50 + 4 and 60 + 3. Here is an example of the grid method used to multiply 254 × 63. Grid method multiplication may also be referred to as box method multiplication or grammar school multiplication. These results are written in a grid and the final answer is found by adding them up to make a total. It involves partitioning the numbers into their place value columns and multiplying each part separately. The grid method is a written method of multiplication that is used to multiply two numbers that contain more than one digit. What is the Grid Method of Multiplication?
