Casio PRIZM or PRIZM Color Grapher[1] is a series of programmable graphing calculators (succeeded by Casio ClassWiz CG) introduced by Casio in 2011, notable for their high-resolution backlit color display, photo graphing capabilities, and "textbook" mathematics rendering and entry.[2] They are permitted on all major standardized tests including ACT, SAT, AP, GCSE and A-level examinations.[3]
Transition from PRIZM to Classwiz CG
The Casio PRIZM series of graphing calculators was announced in 2010 for release in 2011[4] with the North American "PRIZM fx-CG10" and "PRIZM fx-CG20" variants, simply referred to as the "Casio PRIZM".[3][5]
Although Casio had released other models with a color display as early as 1996,[6] the PRIZM represented Casio's first full-color model. Together, the fx-CG10 and fx-CG20 were the world's first "full color"[5] graphing calculators (the earlier models only capable of displaying a handful of colors).
Featuring a faster interface,[7] an expanded feature set, and a cosmetic redesign, Casio's fx-CG50 was released in 2017[8] as the last of the PRIZM lineup.[5]
In 2024, at the National Council of Teachers of Mathematics (NCTM) Annual Meeting, Casio announced the "fx-CG100 ClassWiz CG"[9][10]—successor to the PRIZM fx-CG50. While previous "Color Graphing" models bore the PRIZM name, the fx-CG100 is the first in the CG lineup dubbed "ClassWiz".[5] The label was established for some of Casio's more recent calculators, characterized by a redesigned user interface and design language.[11]
Setting the fx-CG100 apart from other ClassWiz models, which lack the color graphing capability that has defined the CG series, the fx-CG100 carries the distinct "ClassWiz CG" label, effectively replacing PRIZM as the marker of Casio's premier color graphing lineup.[5]
Industry adoption of color displays
Though first to market, Casio only narrowly preceded Texas Instruments in the release of their first color graphing calculator—the TI-Nspire CX, also released in 2011.[12][13] HP followed suit with the HP Prime in 2013.[14] In 2015, TI followed with the TI-84+ CE[15] as the newest addition to the TI-83+/TI-84+ series that has dominated US classrooms, bringing color display technology to the most popular graphing calculator series in the country.[16]
