Lattice Method Made Easy: A Simple Way to Multiply Big Numbers
Struggling with long multiplication? You're not alone. The lattice method is a fun, visual way to break down big multiplication problems into smaller, easy steps. Whether you're just starting or want a cleaner process, this grid-based technique helps you stay organized and get the right answer with less confusion.
What is Lattice Method Multiplication?
Lattice method multiplication is a visual technique that uses a grid to simplify multiplication. Instead of carrying numbers as in the traditional method, this approach places each multiplication into a separate box in a lattice, organizing partial products by diagonals. It helps reduce mistakes and supports clear thinking, especially for students learning how to multiply large numbers.
How to Do Lattice Method Multiplication – Simple Steps
Let’s learn this with a real example: 23 × 36
Step 1: Draw the Lattice Grid
Create a 2×2 grid (since each number has 2 digits).
Step 2: Label the Grid
Write 2 and 3 (digits of 23) across the top.
Write 3 and 6 (digits of 36) down the right side.
Step 3: Draw Diagonals
In each square, draw a diagonal from the top right corner to the bottom left.
Step 4: Multiply and Fill the Boxes
Multiply the digits from the top and side.
2 × 3 = 06
2 × 6 = 12
3 × 3 = 09
3 × 6 = 18
Place the tens digit above the diagonal and the ones digit below.
Step 5: Add Along the Diagonals
Start from the bottom right:
Diagonal 1: 8
Diagonal 2: 2 + 1 + 9 = 12 (write 2, carry 1)
Diagonal 3: 6 + 0 + 1 = 7
Diagonal 4: 0
Step 6: Read the Final Answer
Start from the top-left and follow along the diagonals: 828 23 × 36 = 828
Why Use the Lattice Method?
Breaks large problems into small steps
Visually clear and structured
Reduces carrying and alignment errors
Helps in building times table fluency
Engaging and easy for all learners

Lattice Method vs. Vedic Math: A Quick Comparison
Lattice Method is a visual multiplication technique that uses a grid to break calculations into smaller parts, helping students organize and simplify large problems step by step.
Vedic Math, on the other hand, is an ancient Indian system built on 16 sutras (formulas) and 13 sub-sutras. Rediscovered by Bharati Krishna Tirthaji, it focuses on mental math, shortcuts, and fast calculation strategies, often without pen and paper.
Moderate – encourages number sense through finger use
Fun/Engaging Factor
Medium – can be fun to draw and follow
High – turns your hands into a calculator
The Lattice Method is great for visual learners, while Chisanbop works well for kids who prefer hands-on learning. Choose what suits your child’s style best.
Make Multiplication Easy with the Lattice Method – Fun Math Learning at Interval Learning!
The lattice method of multiplication is a powerful visual tool for students who are starting to learn or struggle with multiplication. It breaks down large numbers into small, understandable steps and reduces common math errors.
While it’s not a mental math method like Vedic math or abacus, it builds strong foundational understanding.
At Interval Learning, we believe every child can learn math with the right techniques. Our non-academic Vedic math courses are designed to make learning math engaging and fun.

The best method depends on your child’s learning style. Visual learners may benefit from the Lattice Method, while hands-on learners might prefer Chisanbop. Techniques from Vedic Math also help children improve speed and accuracy in mental math.
Vedic Math offers quick mental calculation techniques based on patterns and logic. While traditional mental math builds step-by-step skills, Vedic Math can make solving complex problems faster and easier.
Yes. Vedic Math complements other mental math strategies like the Lattice Method and Chisanbop. Using them together can help children strengthen their overall math understanding.
Children as young as 8–10 years old can begin learning Vedic Math and mental math techniques. Starting early helps build strong number sense and boosts confidence in solving math problems mentally.
Mental math is the ability to solve mathematical problems in your head without using paper, calculators, or other tools. It improves focus, memory, and calculation speed, and is especially helpful for day-to-day problem solving.
