Why Teach the Times Tables at All?

Posted by: 

Some noted mathematics scholars have suggested that students don’t really need to know the times tables.  They argue that the process is all they need to understand. 

I totally agree that students need to know the underlying concept of what multiplication is, but I also see the importance of students knowing the multiplication facts. The number one complaint I hear from middle school and high school teachers is how students struggle with algebra, geometry, and other math classes when they don’t know the multiplication facts.
