I'll add some links to this page to help further explain our work with multi digit multiplication:

Array/Area/Box Method Students will surely recognize these:)
These video clips demonstrate methods we've used in class and how they're connected to the standard algorithm.

Here's a great visual and musical way to get the foundation of array multiplication:)

Bowtie
Here's another multiplication method called the BOWTIE. The kids love this fun way to keep track of the numbers we're multiplying.

Lattice Challenge We haven't used this method in class.
It's a fun way to multiply. Go ahead & take the challenge! You can do it.
