    Note: This is a re-post from 2013, dedicated to Dr. Golden’s students!   Liu Hui was a 3rd century Chinese mathematician. I first stumbled upon him when I saw puzzles based on dissection proofs of the Pythagorean Theorem (Shang Gao Theorem (商高定理)) at ICME11 in 2004. Recently I’ve been exploring the trisection of a...

    You Can Never Leave

    I just read my last post – from more than a year ago! Clearly, I’ve been busy, and I’m not done with my work at Discovery Education. Thankfully, Patrick keeps finding new things for me to do. I spent some time last fall as a technical editor for Coach and Practice problems; that was interesting because I...

    Wrapping-Up and Moving On…

    My consulting work at Discovery Education is concluding, so I’m looking for a new creative endeavor in secondary math to which I can contribute. My main interest is in lesson design, with a focus on open-source technology integration. I like to work in a collegial atmosphere, but to do so remotely. I’ve seen that this can be...

    I had a really good day at the Ten Counties Math Association Conference in New York State. My table was at the end of a hallway with reps from TI, Houghton-Mifflin, and Casio. People who asked about the ProRadian Protractor company were surprised to hear that I am the whole company! (OK, full disclosure:...

    Oh, Commerce

    So, it’s 3:30 am, and I am wide awake in a hotel room, awaiting my now-redundant 5:15 wake-up call. I am filled with nervous energy because today I am exhibiting my ProRadian Protractors for the first time at a math conference. I’ve done several workshop presentations, the first of which had 96 attendees, but this...

    Not Just Any Day

    So, I read about this week’s MTBoS task on a day full of challenges and changes for me, but I decided to write about it anyway. You see, I resigned today from my position as Program Manager at a Regional Education Support Center. Not because I don’t love the work, or the people, but...

    O’Beirne Puzzle

    by  • October 9, 2013 • 0 Comments

    I was on Twitter one night recently (that never happens) and someone replied to one of my tweets, encouraging me to look at Richard Thiessen’s posts at aimsedu.org. So, I did. What caught my eye, and my imagination, was the O’Beirne Puzzle. So cool! Last night, I made my own, with my amazing husband’s help....
