Practice the Hindus method of multiplication. Lattice multiplication is a simple technique that breaks long. In previous posts, we talked about The Ancient Egyptian Multiplication method and the Russian Multiplication Method which are very interesting methods to teach as well. It encourages creative and flexible thinking and allows students to discover different ways to view concepts and carry out computations. Incorporating the history of mathematics in math lessons based on the studying concepts ignites the students’ interest in math and increases their motivation. Teachers know well that students need to be presented with alternate ways of solving a problem so that they can adopt the one that works for them. Moreover, it is important to show our students that there is more than one way to solve a problem. These are both important skills that students need to master for solving multiplication problems. It is a great algorithm to teach elementary students because it organizes the problem around a grid, based on place value and uses the distributive property of multiplication.
The Hindu multiplication is an ancestor of the methods we use at school today. The tens add up to 16 to we need to regroup. Next, add the numbers along the diagonals. The diagonals separate the digits of the products into 4 columns. This is how the lattice will look once you are done multiplying. If the product for a cell was just one digit then you would write 0 in the tens place. Multiply the numbers and write 21 with the tens’ digit above the diagonal and the one’s digit below the diagonal. Next, find the cell where 7 and 3 intersect. Its usually used when solving problems, which include. Write 35 so that the tens’ digit is above the diagonal and the ones’ digit is below the diagonal.Ĭontinue the same way. Lattice multiplication, also known as Chinese multiplication, is a written method of multiplying numbers.
