Mastering 4.4D Lattice Method Multiplication

This video tutorial provides a guided practice on the lattice method for multiplication. It covers one by four digit and two by two digit multiplication, demonstrating how to use the lattice model to find partial products and sum them to get the final product. The tutorial also includes instructions on drawing your own lattice for multi-digit multiplication, ensuring learners can apply the method independently.
