Friday!

Need to get away from twitter which has a mess of stuff from another open education summit.  Sour grapes. I did the next two (now down to 16 lessons) ALEKS lessons … the figuring out angles and sides of a triangle with laws of cosines and sines.    Talk about exercises in precise attention to […]

Fellow…

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 […]

Arduous efforts

It’s neat when people are working hard… and getting stuff done.   (Wish:  that the stuff were better designed so that I didn’t need to help with navigation, and we could focus on the math.)   There was much “productive struggle” happening. The analogy of the day:   “Tricks” such as arbitrary memorized “scaffolds” and […]

Decimation is literally losing 1 in 10 people;   if I remember correctly it was a strategy used for discipline in somebody’s army.   The 90% remaining would buck up and behave, in abject fear. Most usages these days involve losing more than 10%, but I’m thinking our current college situation is similar.   http://www.news-gazette.com/news/local/2016-06-28/talent-learning.html    […]

I was out marking roads for our upcoming bike ride during yesterday’s webinar on the latest THING THAT IS GOING TO SAVE ALL MATH INSTRUCTION BECAUSE IT IS SO GOOD AND AMAZING. I think I’m glad I get to watch it because I don’t really want to be commenting “live…”  through the initial cynic filter… … […]

Why leave the visuals behind?

On my twitter feed, Steve Wyborney posted an awesome little graphic which I am stealing and posting below:  He asks that if somebody uses it in K-2, to “take a pic of your board and send my way!” Then there’s the awesome Donna Boucher who has all kinds of resources on her site for making […]
