Decimated Decimals

June 27, 2014


Hmmm… while I’m working on my Tone of Voice, I should prob’ly do the same for the tone of my digital communications. A poster plopped onto Facebook with pictures of foods and their prices; the salad was $4.99 and a burger and a coke were each labeled as “.99” cents. I felt compelled to contact […]

pie our squairs

June 26, 2014


pie our squairs… we often show why the area of a rectangle is the length times the width or the base times the height, but students so often get even more confounded with area vs. circumference of a circle.  I’m thinking of including in My Idea Of A Pretty Good Math TUtorial a sidebar with […]

focus, focus, who’s got the focus?

June 25, 2014


Doesn’t help that the flash drive with the most recent version of my app is AWOL… but… time to get back to it anyway.   The advantage to not having spent more than an hour or so on it is that … it shouldn’t take more than five times that long tocatch up, eh?    […]

“FrontRow” MOS

June 23, 2014


   When I stumble across a new program for “differentiated math instruction” (always, ALWAYS Aligned To The Common Core)… just gotta give it at least a brief once-over. is today’s.   I really like the option to click for a sketchpad so you can draw on the screen. I also like the “virtual […]

Site list that I like!

June 13, 2014


Usually, peoples’ requests via email to be added to my site are…almost as sad as my site, which I created in pre-CSS days and don’t like my provider at all and need to migrate it somewhere better and… and…   but this one is worth sharing: Now, I’m not endorsing anything else about the site, about […]

The power of a small group…

June 13, 2014


… naw, not even a “small group.”  A “few people” not even grouped may have all kinds of power for influencing online spaces and turning them into communities, or at least making them viable spaces. The Udacity MOOC for “algebra review” might be an example of that.   I logged in just to see what […]

What’s taught vs. what’s learned

June 11, 2014


A student is reviewing for our assessment test, and going over “simplifying expressions.”  She is learning that u^2 + 1 + u – 1 is u^2 + u… … she will probably understand which combinations of letters and powers can be added and which can’t.  However, with the kind of examples and instruction in “test […]

Calculators, Calculators and MOOCS

June 9, 2014


I’m looking atthe questions people are posting at the Udacity MOOC (where “LisaB” is awesomely helping people so I wonder if she’s in a situation like mine at a desk with not much going on right now)…  … questions seem to fall into two categories:  “WHY DON’T I GET THERIGHT ANSWER???”    without any information […]

a note about Makin’ Stuff.

June 5, 2014


Yes, I entered the #WorksWonders contest for Doing Educational Things with Microsoft Office.  It was almost a no-brainer, because yes, I figured out that powerpoints and narrated powerpoints work well for my students — especially with a little bit of animation thrown in.   Turning them into YOuTube videos — not so good, since you […]

Thoughts on MOOCs and math teachers

June 4, 2014


So I’m looking more at the MOOC and noticing how many comments have a student really frustrated, or saying the course isn’t doing them any good.   THe cool thing about this one is that there is feedback… from people who know what they’re talking about, usually.        I did smack into another […]
