1. When and where did MathTree begin?

MathTree began in 1999, as Salvo Educational Enterprises. Lynn Salvo, the founder, held small camps in two locations that year, and taught them herself. One camp was at the Washington Waldorf School in Bethesda, MathTree’s first dignified venue. The other venue was humble -- the basement of the VFW Post in McLean, VA. Though it was cool in spite of the summer heat, it reeked of alcohol and tobacco from upstairs. Since its modest beginnings, MathTree has been hosted in venues such as:
  • Sidwell Friends School, Washington, DC
  • Langley School in McLean, VA
  • Flint Hill School, Oakton, VA
  • Georgetown Day School High School in Washington, DC
MathTree was incorporated as MathTree, Inc., in 2001.

2. Who started MathTree?

Lynn Salvo, Founder and President of MathTree, Inc.

Lynn Salvo is founder and president of MathTree, Inc. She started MathTree because she loves teaching children math, explaining it so children “get it,” and she truly enjoys seeing a child’s face in the moment when s/he “gets it.” Her company has been providing summer math camps for children since 1999.

Dr. Salvo received her PhD in Math Education Leadership from George Mason University in 2006. The title of her dissertation is Effects of an Experimental Curriculum on Third Graders' Knowledge of Multiplication Facts.

Dr. Salvo has produced numerous original materials for the teaching of math including Multiplication Matters, the curriculum she developed for her dissertation research and refined on the basis of her research results; Divide and Conquer, a conceptual curriculum on division; Much Math in a Minimum of Morsels, a book about elementary number theory, her favorite branch of mathematics; the MathTree® curriculum, the 200-skill diagnostic system used to develop individual student skills at MathTree Math Camps. She created Product Parfait, a game that makes players think about multiplication from a point of view different from the usual, which is scheduled for publication by Didax, Inc., in January 2009. She also created the Remainder Race, a game that develops facility with divisibility rules. She has two patents for devices to teach the math concepts of odd and even and the value of the number p. She has presented numerous papers and workshops at international, national, and local conferences for math teachers. For more extensive details, you may refer to her Curriculum Vitae.

Dr. Salvo is also an avid athlete. The peak events of her athletic career were the Boston Marathon (April 21, 2003) and the Eagleman Triathlon (a half-Ironman triathlon, June 8, 2008). She uses her math to check her pace and predict her finishing times in her athletic events.

3. Why do you do what you do?

We love math, we love kids, and we love teaching kids math. From our adult perspective, we are aware of the continuum of math skills. When we teach a young child what a fraction means, we know that one day our explanation may help that child understand trigonometry. And when we work with a teenager who is taking calculus and who is trying to cope with implicit differentiation, we can tell that the student was never truly taught deeply about the number one.

4. How do you do it?

We teach math in multiple modes, inspired by the Lesh translation model. Lynn Salvo, founder of MathTree, considers this model the most important nugget she got from six years in her Mathematics Education Leadership PhD program.
(retrieved 12/31/08 from http://cehd.umn.edu/rationalnumberproject/03_1.html)
Lynn Salvo’s personal philosophy of mathematics education permeates the camps.

The MathTree skill development curriculum used in the camps was approved in 1999 for use in Fairfax County Public Schools (FCPS). FCPS is the twelfth largest public school system in the US (by number of students enrolled). Since then, Lynn Salvo has developed numerous curricula that are proprietary to MathTree camps.
