    After teaching for 14 years, I now design curriculum and create digital and print instructional materials for high school and middle school math. I have also invented and am now marketing radian-scale protractors. Check out www.proradian.net! I'm very happily married and have 2 grown sons and a cat named Louie.

    I had the privilege of working with five motivated and thoughtful teachers this week who will be teaching our Geometry21 course this year. I had about six hours to show them what this course is all about and make them understand what blended learning looks and feels like. I think it will be a...

    A New Way to Build a Geometric System

    This is a quick preview, I will expand upon it when I can. Here is the outline of another approach to the beginning of Geometry, where each major step can be observed through software or manipulatives, since they are visually obvious, or demonstrated through coordinate geometry. Some must be postulates, others can then be...

    A week or so ago, the folks at MathMunch posted a piece about rhombic dodecs. Well, I love solid geometry, and it tied into my earlier study of honeycombs, so I was quickly hooked! I revised the nets they provided using GeoGebra, so I could locate the center of each rhombus to attach a magnet. I printed them...

    One of the math teachers I follow on Twitter, Michael, made this great program to illustrate that inscribed polygons formed by connecting the midpoints of the prior polygon (concave or convex) will converge to a convex polygon. Try it: Not only is it super-cool mathematically, but it’s gorgeous! I couldn’t resist, I used some...
