Robert Ikeda

I am working on MathPapa, a free algebra calculator that uses interactive diagrams and step-by-step explanations to make middle-school math more intuitive.

My MathPapa Tumblr focuses on middle-school math education and technology.

I made a brief tutorial site on adding fractions.

I will be posting interactive algebra lessons at Variable X.

Past Projects

• DB-Class Exercises: I developed the checking software and interactive workbenches for all of the automatically checked exercises in Prof. Widom's Fall 2011 public class on databases, now hosted by Coursera.
• PyClaycloud was a side project for sharing and rapidly prototyping Python scripts. It runs on Google App Engine.
