Space update
From Washington, DC, right after the NCTM national meeting.By Saturday afternoon, the convention center was a ghost town. I gave my talk on Space to a room where fewer than five percent of the 400 chairs were occupied. I had succeeded in shortening the talk, and didn't need to rush quite as much as I… Continue reading Space update
Space
I added a fair amount of material to my Space page, in time for my presentation about the course this week at the NCTM National Meeting in DC. (If you're attending the meeting, my talk is Saturday, April 25, at 12:30 p.m., in Room 202B in the Convention Center.)--Henri
Abstract Algebra, follow-up
I added a paragraph to the Abstract Algebra Teachers' Guide, just in time for my NCTM presentation in DC. I'll be speaking on my Space class, and expect at least some of the participants in my workshop to head to that page on my site.The talk is Saturday, April 25, at 12:30 p.m., during the… Continue reading Abstract Algebra, follow-up
Abstract Algebra
Not long ago, I received some advertising for class sets of Rubik's cubes, which are sold along with a solving method. Soon afterwards, a correspondent wrote:I see on your website that you have done some work with kids on Rubik's cubes and group theory. I have purchased a class room sets of the Rubik's Cubes… Continue reading Abstract Algebra
Complex Numbers
I added the core of a unit on complex numbers to the Algebra 2 page.Like some other materials I've written over the years for my students at the Urban School of SF, these lessons were inspired by the pioneering work of Stein, Crabill, and Chakerian (see their out-of-print Algebra II/Trig book.)From the intro to the… Continue reading Complex Numbers
12-month leave
I recently started a 12-month leave from teaching. This may give me some time to add materials to this site. I've prioritized the many items on my list, so you may see them appear as time permits. If you have requests, now is a good time to let me know!I just uploaded a slightly updated… Continue reading 12-month leave
The Final Frontier
I updated the page on my Space post-algebra 2 advanced geometry elective. I added a fair amount of additional details based on this year's iteration of the course.I also gave a talk about the course today, which suffered from a bit of a tech meltdown at the end, as I had trouble going back and… Continue reading The Final Frontier
Logo Math
I removed the book / software package Logo Math: Tools and Games from my publications page, as it has been out of print for some time.The vision it manifested, articulated in "The turtle in the age of the mouse", is nearly defunct as well -- I know of no currently available programming language that can… Continue reading Logo Math
Showing Work
From a correspondent: "I recently came across a math teacher that has a policy of providing a "zero" on any math homework assignment where the student does not show his/her work. The math teacher has informed the building principal that showing the work, i.e., the process is required for the student to learn math. This… Continue reading Showing Work
