How to Use Lattice Multiplication
Using lattice multiplication is relatively straightforward, and with practice, kids can become proficient in this technique. Here’s a step-by-step guide on how to use lattice multiplication:
To start, kids need to create a lattice or grid to represent the multiplication problem. The lattice should have the same number of rows as the first number and the same number of columns as the second number. For example, if kids want to multiply 4 x 5, they would create a lattice with 4 rows and 5 columns. Next, kids need to fill in the lattice with the partial products, which are calculated by multiplying the numbers in each row and column. Finally, kids need to add up the partial products to get the final answer.
Example of Lattice Multiplication
Let’s use the example of 4 x 5 to illustrate how lattice multiplication works. To start, kids would create a lattice with 4 rows and 5 columns. Next, they would fill in the lattice with the partial products, which are calculated by multiplying the numbers in each row and column. The partial products would be:
| Row 1 | Column 1 | Column 2 | Column 3 | Column 4 | Column 5 |
|---|---|---|---|---|---|
| 4 | 4 | 8 | 12 | 16 | 20 |
| 3 | 3 | 6 | 9 | 12 | 15 |
| 2 | 2 | 4 | 6 | 8 | 10 |
| 1 | 1 | 2 | 3 | 4 | 5 |
Finally, kids would add up the partial products to get the final answer, which in this case would be 20.

What is lattice multiplication and how does it work?
Lattice multiplication is a visual method of multiplying numbers that involves creating a lattice or grid to help organize and calculate the product. This technique is particularly useful for kids, as it provides a hands-on and intuitive way to understand the concept of multiplication. The lattice is typically divided into rows and columns, with the multiplicand (the number being multiplied) written along the top row and the multiplier (the number by which we are multiplying) written down the left column. Each cell in the lattice represents a partial product, which is calculated by multiplying the corresponding digits of the multiplicand and multiplier.
The lattice multiplication method works by breaking down the multiplication problem into smaller, more manageable parts. By calculating the partial products and adding them up, kids can arrive at the final product. For example, if we want to multiply 43 by 27 using the lattice method, we would create a lattice with 43 along the top row and 27 down the left column. We would then calculate the partial products for each cell, such as 40 x 20, 40 x 7, 3 x 20, and 3 x 7. By adding up these partial products, we can find the final product of 43 x 27. This method helps kids to develop a deeper understanding of the multiplication process and can make it easier for them to calculate products, especially for larger numbers.
