He's an impressive mathematician with real credentials, but what I like best about him is his straightforward, common sense way of talking about things. He's direct and clear, and funny. In school I… Continue reading Paul Lockhart on Teaching Math

## How Classical Education Shapes Mathematical Thinking, by Jon Gregg

“The study of mathematics develops and sets into operation a mental organism more valuable than a thousand eyes because through it alone can truth be apprehended.” Plato, The Republic A Misconception Often, even from an early age, certain students develop an affinity for mathematical and scientific thinking, an affinity which parents, teachers, and administrators tend… Continue reading How Classical Education Shapes Mathematical Thinking, by Jon Gregg

## The Singapore Method for Elementary Mathematics

Dear parents, Have you ever heard someone say, “I’m just not a math person?” When I was younger I used to say it all the time, and I hear it all the time from our students (though less and less these days). A lot of people have the idea that you’re either good at reading… Continue reading The Singapore Method for Elementary Mathematics
