The Mortensen Method is concept-based teaching. Jerry Mortensen was Montessori trained, so of course his methodology is based on Montessori principles and teaching.
You'll see PDFs and videos that help you get the concept across to your students or children.
Using concepts makes math fun and easy because once the child understands concepts all we can do is change the numbers.
The concept shown above for example is a simple concept but numbers are made up of other numbers, The child is building Addends past 10.

This entire website can be boiled down to these five concepts, & variations around these five themes.
The Five Basic Concepts:
1. Mathematics is the study of numbers and all we can do with numbers is COUNT
2. The concept of SAME. The highest number we can count to (in base ten) is 9, the numbers tell you how many the places tell you what kind. Before we can count they must be SAME.
3. We form rectangles to facilitate counting.
