Our program was designed by UCLA professors of mathematics, immigrants from the Soviet Union. The roots of the program lie in the Eastern European Math Circle movement pioneered by the Soviets. However, the program was further developed to prepare American children for success in the 21st century American college and beyond. Our aim is graduate and post-graduate education and research.

From the founders

The driving force behind this company is our desire to prepare children for the challenges of the 21st century global economy based on information technology. To do that, we have to start early. We need to introduce children to many more areas of modern day mathematics than the ones covered in the traditional school curriculum such as graph theory, combinatorics, algorithms, etc. We also believe that thinking is a craft with its own skillset. Math is just the most convenient playground for training a person skillful at thinking a.k.a. smart.

Our philosophy

The first pillar of our teaching philosophy is the idea that math is an ultimate form of art. When taught properly, math is even more entertaining than it is empowering. Here is an example of a problem we find very beautiful. Two ladies are sitting in a street café talking about their children. One says, "As you know, I have three daughters. The product of their ages equals 36. The sum of their ages equals the number of the house across the street. Would you be able to figure out how old each of my daughters is?" The other lady writes a few lines on a napkin and responds, "You didn't give me enough info." "Oh yes," agrees the first lady and adds, "my oldest daughter has beautiful blue eyes." Then the second lady figures out the age of each girl. Please note that the problem has a unique and not that hard to find solution. The second pillar of our teaching philosophy is that the curriculum should closely follow progress in science and technology, not trail a century or more behind. For example, the material we teach to students in grades 1 through 5 includes combinatorics, recursive algorithms, 4-dimensional geometry, topology, algebra of logic and microchip design, encryption, game theory, and more.

What to expect

The topics we teach at 21st Century Math go far beyond the standard school curriculum. By attending our program regularly for a number of years a student will get a well-rounded overview of topics from all fields of mathematics, from algebra and number theory to geometry and topology, including the modern day applications to cryptography. Whenever you join the 21st Century Math, you should not expect to understand everything right away. You will understand more and more as you get more experience.
