Fellow…

March 21, 2017

Possibilities abound.   EngageNY is looking for “fellows” to help develop their curriculum.  Oh, my, it is full of the vilified “not your parents’ algorithms” terms like “Hide Zero Cards,” which a quick search informs me are manipulatives for reinforcing that, say, 13 is really 10 + 3 — you represent 13 with a ten card […]

Formulae are abstract.   Substitution into a formula can be a meaningless machination.  No longer, for the student who explained what we’d have to do to find the missing length knowing perimeter and side of a rectangle… double the width and subtract it from the perimeter.   Well….

Hmmm…   It’ll be on my grant list 🙂  (It’s over a hundred dollars on W00t today.. and I […]

An entirely too-long blurb yesterday morning on Weekend Edition was about a “rabbit hole” — the thing that happens when you get online and click from one thing to the next.      I’ve had some awesome opportunities come up from going down rabbit holes… but they’ve reached a critical mass where I need to […]

So, I figured out how to skip all the parts with Git and GitHub and pushing and pulling and what have you… and I’ve got the “app-release” version “pre-beta” at https://www.dropbox.com/s/t8n28c2yr321q3n/app-release.apk?dl=0  … and I told a few people about it.
