The first time I saw the Lattice Multiplication method was
from my daughter who was in 4th grade at the time. My first thought
of this method was that it was crazy and messy. At first I didn't understand the
concept and could not help my daughter with her double digit multiplication
problems using the lattice method. While helping her I was wondering what
happen to teaching children the “old fashion way” where you line your
multiplication problem is columns.
I never did get the method of Lattice Multiplication until
for my class “Math for Elementary Teachers”. My teacher has us watch a YouTube video that showed step by step instructions that helped me to understand this
method. Now I will be able to help my own children entering 4th
grade and 2nd grade to understand the lattice method along with my
future students.
After looking into the Lattice Method I found that it is the
same as regular long multiplication, however, it breaks the process into
smaller steps, which some people find easier to use and understand. I can see
why some individuals prefer the lattice method over long multiplication. In
this day and age it is great that we have many different options/resources to
help individuals that struggle with long multiplication.
There are some resources that are available to teach the Lattice
Method:
