Experience
I have over 25 years of experience as a Curriculum Developer and Research Director, specializing in hands-on mathematics and logic puzzles for elementary students. I have developed various creative math programs focusing on spatial reasoning and geometry.
Teaching style
My approach is 'Play to Think'. I believe the best learning happens when students are so immersed in a puzzle that they don't realize they are doing complex geometry. I create materials that turn passive listeners into active problem solvers.
