It was created in the 9th century by Al-Khwarizmi and brought to Europe by Fibonacci. The lattice method is also called Shabakh and is a method of multiplying two numbers using a lattice. Who Invented The Lattice Method Of Multiplication? This will become obvious with multi-digit multiplication and division. The advantage of the lattice method is that the student doesn’t have to worry about where to insert numbers the template maintains them in place. What Are The Advantages Of The Lattice Method? Once you have multiplied, your answer is on the outer edge of your lattice. Once you have the lattice set up correctly, you will need to draw diagonals through these boxes to assist with the multiplication process. Its usually used when solving problems, which include. My sons were taught to make a grid on their paper. Lattice multiplication, also known as Chinese multiplication, is a written method of multiplying numbers. I used a second green rod to underline the row I was going to use. Lay down the row number rod (mine is green). In order to use Napiers rods, you find the rods that make up the longer number. The following diagram shows an example of lattice multiplication, step by step. For example, a 2-digit by 2-digit problem would have 2 columns and 2 rows. Step 4: Using the Rods: 2 Digits Times 1 Digit. A series of free, online Grade 4 Math Lessons with video lessons, examples, solutions, worksheets and activities. Lattice is constructed based on the number of digits being multiplied. ![]() ![]() This method begins with the construction of a lattice that is sized to fit the numbers being multiplied.
