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. We simply increase the numbers of rows or columns based on the number of digits in the factors. 9x981 9 (one digit) multiplied by 9 (one digit) equals 81 (two digits). These are both important skills that students need to master for solving multiplication problems. 3 (one digit) multiplied by 2 (one digit) equals 6 (one digit). 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. Once your students have mastered simpler lattice multiplication grids, have them try these large 3-digit by 3.
#LATTICE METHOD MULTIPLICATION 3 DIGIT HOW TO#
The third book models how to multiply a 3-digit number by. Lattice Multiplication : 3 digits by 3 digits. This is how the lattice will look once you are done multiplying. The second book practices using the Lattice method to multiply a 3-digit number by a 2-digit number. 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. Great for classroom teachers, homeschool moms and dads, or parents of kids in school.īelow you'll find lattice multiplication template worksheets with multiplication problems for students to work out.Write 35 so that the tens’ digit is above the diagonal and the ones’ digit is below the diagonal.Ĭontinue the same way.
These worksheets have the multiplication problem along with the appropriate black lattice multiplication grid to work the problem along with the worked out solutions on a separate page. Ok, so maybe you'd like some lattice multiplication worksheets with multiplication problems for your students to practice.
To learn how it works, click on this lattice multiplication link where we break it down for you step-by-step. If you haven't jumped on the lattice multiplication bandwagon yet, go on over to our lattice multiplication page that teaches the lattice multiplication process. Lattice multiplication is just another way to multiply numbers and may even be for some students. If you're new to the whole lattice multiplication thing, no worries. By the way, if you don't see the multiplication template here, let us know and we'll provide it just for asking. Here's a great video on how to do lattice multiplication.
