Mastering Multi-Digit Multiplication Techniques

The video tutorial introduces fourth graders to three methods for solving multi-digit multiplication: the standard method, the box method, and the lattice method. Miss Julie demonstrates the standard method using the example 414 times 37, explaining each step in detail. Miss Julia then explains the box method, breaking down the numbers into place values and multiplying each separately. Finally, Miss McKinsey demonstrates the lattice method, using a grid to organize the multiplication process. Each method results in the same final answer, fifteen thousand three hundred eighteen.
