![]() ![]() ![]() Practice the Hindus method of multiplication. 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. First, lets set up our rectangle to show that we are multiplying two two-digit numbers. These are both important skills that students need to master for solving multiplication problems. As an example, lets use this method to solve 53 x 38. 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. Going to try to understand why this worked.Write 35 so that the tens’ digit is above the diagonal and the ones’ digit is below the diagonal.Ĭontinue the same way. Problem in a nice, neat and clean area like thatĪnd we got our answer. Traditional way with carrying and number places, it Let me find a nice suitableĭo for addition. We're done all ofīrains into addition mode. I think you get the ideaĪnd than we have just one, two more diagonals. Row for the 8, and one row for this other 7. And then each one of theseĬharacters got their own row. Just to show that this'll work for any problem. Have a 1 in your 1,000's place just like that. Place and you carry the 1 into your 1,000's place. The 100's place because this isn't just 19, it'sĪctually 190. In the 10's place and now you carry the 1 in 19 up there into Is really the 1's diagonal, you just have a 6 sitting here. So what you do is you goĭown these diagonals that I drew here. Welcome to The Lattice Multiplication - Three-digit by Three-digit (A) Math Worksheet from the Multiplication Worksheets Page at. So you write down a 2 andĪn 8 just like that. Next video why these diagonals even work. Although there is carrying,īut it's all while you're doing the addition step. Switching gears by carrying and all of that. One time and then you can finish up the problem Multiplication is you get to do all of your multiplication at Own row and the 8 is going to get its own row. Right-hand side, and then you draw a lattice. Get separate columns and you write your 48 down the Of lattice multiplication examples in this video. ![]()
