Multiple Digit Multiplication

2 Digit x 1 Digit Multiplication
For the past couple of weeks we have been learning multiple digit multiplication. First, students learned about 2 digit by 1 digit multiplication.



















3 Digit x 1 Digit Multiplication
Next students learned 3 digit by1 digit multiplication. We talked about how this was just one extra step because it was just one extra place value.


 
2 Digit x 2 Digit Multiplication
Finally, students learned 2 ways to multiply 2 digit by 2 digit numbers. The first method is called the turtlehead method. Most students chose to use this method.






































Here is a video we watched in class to help us remember the turtlehead method:

Sorry, for some reason it's not letting me embed the video to this post.

Another method students learned was the Box Method. Some students may find this way to be easier. As always I tell students to use whichever method they are most comfortable with. They always have options.
