![]() ![]() ![]() The lattice method can be extended for numbers of any size, and even for decimals, and it’s a good way to visually understand how multiplication works. Preview images of the first and second (if there is one. Use the buttons below to print, open, or download the PDF version of the 5-Digit by 5-Digit Lattice Multiplication (A) math worksheet. In this case, the product of 23 and 45 is 1035. Student s can use math worksheets to master a math skill through practice, in a study group or for peer tutoring. So, write these sums next to the corresponding diagonal, from top to bottom: 0, 1, 3, 5. The leftmost diagonal has only one number: 0 (from the 08 in the upper box) Place one factor on top of the lattice, the other on the side.The next diagonal has 1 (from the 12 in the upper box), 0 (from the 10 in the lower box), and 0 (from the 08 in the upper box): 1 + 0 + 0 = 1.The next diagonal has 1 (from the previous box), 2 (from the 12 in the upper box), and 0 (from the 10 in the lower box): 1 + 2 + 0 = 3.The rightmost diagonal has only one number: 5.If a diagonal’s sum is more than 9, carry the tens digit over to the next diagonal. The grid should look like this:ĥ | 10 | 15 Step 5: Add Along the Diagonalsįinally, add the numbers along the diagonals from the bottom right to the top left. The top right box is 3 (from 23) times 4 (from 45), which is 12, so write 12 in the box. If the result is a single digit, put a zero in the top triangle.įor example, the top left box represents 2 (from 23) times 4 (from 45), which equals 08, so write 08 in the box. Write the result inside the box, with the tens digit going in the upper triangle (above the diagonal) and the ones digit going in the lower triangle (below the diagonal). Now, for each box, multiply the digit at the top of the column by the digit at the end of the row. This zip file contains 6 pdf files: 3 student practice pages, and 3 answer keys (one for each of practice pages). ![]() The line should start from the bottom right of each square and end at the top left. The 'lattice' part is already drawn in on all three of the student worksheet pages, making it easier for students to focus on mastering the technique, rather than obsessing over setting up the boxes. Your lattice should look like this:ĭraw a diagonal line through each square. Write the second number, 45, along the right side of the grid, one digit beside each row. Write the first number, 23, along the top of the grid, one digit above each column. Step 1: Draw the Lattice Gridĭraw a \(2×2\) square grid for our example because we have two digits in both numbers. Here’s a step-by-step guide on how to use it: This method is quite visual and can help you see how multiplication works, especially with larger numbers.
