In this episode we speak with author, early years math curriculum designer Doug Clements. Doug is a professor at the university of Denver. He’s published over 130 research studies, authored 23 books on early years mathematics. He’s served on the U.S. President's National Mathematics Advisory Panel and he’s a co-founder of Learningtrajectories.org with his partner Julie Sarama.  Stick around while we dive into why we need to think deeply about early elementary mathematics; how we can help students think conceptually about mathematical ideas at a young age; learn about resources you can use at home to strengthen early years mathematics; and, how parental mindset is key in a student's progression of mathematics.  You’ll Learn:  Why we need to think deeply about early elementary mathematics.  How we can help students think conceptually about mathematical ideas at a young age.  Resources you can use at home to strengthen early years mathematics.  How parental mindset is key in a student's progression of mathematics.  Resources:  http://learningtrajectories.org/  Which One Doesn’t Belong [Book]  Learning and Teaching Early Math [Book]  The Van Hieles Model of Geometric Thinking
