Break over!

June 19, 2017

(When I was a lifeguard at little apartment pools, we called the “adult swims” what they really were — breaks for the kids to get out of the water.   We didn’t call them religiously on the hour — and the kiddos usually figured out that they’d get called if they started getting cranky with […]

Alligators to the contrary

I know, I know, students are fond of the alligator always chomping the greater number. Still, I wanted to feature Casey/Gravity 🙂   It behaved rather oddly — the greater than text layer switched to a mirror image of itself… then the dogs switched… I’ve observed with things visual or mechanical that my first attempts […]

Okay, I don’t ‘think visually’ so I couldn’t begin to tell you what a person could make… but I saw this https://www.silhouettedesignstore.com/ready-set-make   and thought… oh, even *I* could make manipulatives… really creative manipulatives… with that thing. Hmmm…   It’ll be on my grant list 🙂  (It’s over a hundred dollars on W00t today.. and I […]
