Van Aubel’s Theorem. Reminded me today of one of the greatest ‘how is that possible’ theorems in plane geometry: Van Aubel’s Theorem. I like that it needs to be squares (or a right isosceles vertex) - it’s not just any corresponding similar point. Also weird that congruent perpendicular diagonals doesn’t make for a specific type of quadrilateral. On GeoGebraTube. What is going on here? Why is it true?

Enter a list of distances. Draw a figure by going the first distance, then making a right angle turn left. Got the next distance, and turn again. When you’ve finished your list, you can go back to the first distance and continue. Here’s the GeoGebra. This is a great place for my favorite math question: what do you notice? I was reminded of these by this post. This is a generalized version of an older sketch. I think from an NCTM journal, but I can’t find the reference. Anything you’d add?

My art teacher friend Heather is thinking up mathart activities with tiles that have matching boundary conditions so that they tile with matching features regardless of orientation. The standard is 4 sides and 2 edge points, but this sketch can do others as well. Play on GeoGebraTube. The bottom two are Heather’s samples. (I know they are infinitely cooler.). What would you do with these? Posted 2 weeks ago. 6 notes • View comments. Posted 3 weeks ago. 18 notes • View comments. Can anyone add to these?

The Futility Closet posted a nice problem. In a game where you can score 3 points and 7 points only, what is the highest score you can not get. (The high not score? It was fun to think about, with great connections to combinations, Diophantine equations and primes, so I wanted to make a visualization. And then a generalization, because why should 3 and 7 have all the fun? So what’s the answer for 3 and 7? For a general s1 and s2? Posted 8 months ago. Yes, the second Mnatsaka. Posted 9 months ago.

A blog for sharing my math interests on the web, to post new materials for elementary, secondary and teacher ed, and vent mathematical steam when needed. Thanks for visiting! Tuesday, March 13, 2018. I keep a close watch on this number line. I keep my eyes wide open for the sign. Making sense, connections all the time. For number sense, I walk the line. Apologies to Johnny Cash. At Math In Action two weeks ago, I presented on number talks in the middle grades. (Here's the handout/resources. As a text, mo...

Place to experiment with wordpress as a blogging platform. August 13, 2012. I got the embed code from GeoGebraTube and switched to the text edit tab to paste it… Let’s see if it works. Thankfully Twitter connects me with people who are better at any given thing than I am, and Laura Kinnel. Figured this out. Here’s her post. With a nifty little position vs time sketch as a bonus. This is not solution for wordpress.com, however, so the quest goes on. Blog at WordPress.com. Blog at WordPress.com.
