This week in math, we have been reviewing some number sense concepts from previous years. One of the skills we’ve gone over is multi-digit multiplication. There are two ways to multiply large numbers: the normal way and the lattice method.
The normal way is the method that most people learn in school. It’s the one where you multiply in columns, regroup, and have to remember to add the zero as a place holder. Most of the fifth graders were fairly comfortable with this method.
The other way we learned is called lattice multiplication. This method is explained very well on this website. Most of the kids were unfamiliar with this method but enjoyed learning it. For some, it was easier than the normal way!
I’m curious to see what method you prefer. So write me some comments about which multiplication method you like better and why. I wonder which method has more fans? Hmmm….
