I got distracted while in my classroom yesterday looking at my old calculators from college days. I thought about them when Sara VenDerWerfshared shared about her calculator museum.
Ever so often I tell my students about my “good ol’ days.” I show them my
- high school (and college) slide rule – IT WORKS
- TI SR 10 (Slide Rule) w/charger but no longer chargeable – receipt for $36.88 (only used for during college chemistry 2nd semester)
- TI-30 LED (9-volt battery) – IT WORKS! initial price of $19.88 (a 1 hour special late evening!) bought 2 years later – maybe used for 1 or 2 college classes (can’t remember for certain)
- I also show them a 1937 book of tables for square roots, logs, and trig given by a parent of one of my former students – it’s really just an older low tech calculator. IT WORKS! (If there’s class time, I tell the story of Napier solving the chicken thief mystery – although there are doubts over the authenticity of that story)
And now I pass on my love for Desmos – so much so that a student wrote my name in tiny Desmos words (maybe about 50-100 “Desmos” per letter of my name) on my whiteboard during an informal lunch study hall. I wish I had a picture of that! This will have to do:
That student moved away before i got to hint at gifting me a pair of desmos socks!!!
