### PRODUCT DESCRIPTION

This resource contains two sheets: one with instructions and one with 6 blank lattice grids. Ideal in math folders for independent practice, as a homework assignment, as a stand alone math center, with parent helpers, or whole group instruction.

Lattice Multiplication has been around for a long time and is featured in Everyday Mathematics as a great strategy for solving large digit multiplication problems.

Basically, it is another way to solve large multiplication problems. It is sometimes called “window” because the grid used resembles a window with streams of sunlight coming through!

Steps:
1. Write the first number horizontally on top of the window so that each digit is over one column.
2. Write the second number vertically at the right of the window so that each digit is next to one column.
3. Multiply the right and top numbers; write the answer in the corresponding box.
4. Repeat step 3 with each pair of numbers.
5. Add the numbers diagonally and write the sum along the bottom and left side of the window.
6. The numbers, in order from left to right are the answer!
