Oddbean new post about login | logout Graphing calculators are dead. Long live graphing calculators. With the SAT going all digital and desmos.com and geogebra providing spectacular visuals the days of the graphing calculator seem numbered. But I have a bold vision for a calculator that would grow with students needs and teach more than math tricks. Just as I've developed a curriculum where students learn about numbers, through to irrationals by making their own wooden ruler this calculator would be a multi-year project. 1/
In 9th grade you learn about boolean logic in geometry and use transistors and logic gates to design a binary adder on a bread board. At the end of the year you plan traces for a PCB, have it printed professionally and solider it. Next year you learn how binary adders are part of the foundation of calculator math, and using a arduino or esp32 based system focus on programming the major functions and controls. Near the end of the year you add a graphics library and start graphing. 2/
