ClassWiz EX Series
ClassWiz CW Series
The new four-tone screen brings gray into the equation, so you can easily tell which part is being entered.
New 'OK' and 'Back' keys are added to a streamlined layout that places frequently used keys close to each other, for easy operation with minimal confusion.
Example
The convex and rounded key faces make them easy to push evenly from any angle.

Variety of Functions and Features
A wide range of essential functions are effective for education and available to support student's learning.
It is easy to select calculator app from the HOME screen that is suitable for the type of calculation you want to perform.
Calculation
Perform general computations using Natural Textbook Display™ notation, including absolute value, logs of any base, summation, derivatives, and integrals.
Statistics
Calculate one-variable statistics (such as sum, mean, max or quartile), and apply linear, quadratic, logarithmic, exponential, and geometric (power) regressions.
Distribution
Investigate Normal, Inverse Normal, Binomial, and Poisson probability and cumulative distributions.
Spreadsheet
Create spreadsheets with up to 5 columns and 45 rows. Spreadsheet supports Fill, Cut/Copy/Paste, recursive formulas, Mean, and Sum commands.
Table
Generates numeric table based on one or two functions.
Equation

Catalog menu shows categories of the commands, functions and symbols in accordance with the calculator app you are currently using and the current status (displayed screen or current settings) of the app.
Inspire Students to Learn
Intuitive and interactive operation makes it easy to use the features of ClassWiz.
By the use of icons, selection of the desired function is quick and easy.
Visual, interactive and textbook-based displays make operation easier for teaching the use of scientific calculators, so you can concentrate on teaching mathematics.
Dice rolls and coin toss simulations are useful for teaching probability, and they offer a fun way of learning with a scientific calculator based on real-life situations.
Each turn produces random results, which then provokes discussion among students.Dice Roll
Up to 250 rolls can be simulated for 1 to 3 dice.
Coin Toss
Up to 250 tosses can be simulated for 1 to 3 coins.
Recursion
The spreadsheet functions makes it possible to enter recursive formulas.
Sequence: a1=2 and an+1 -2an-3 (n=1, 2, 3 ...)
a1-2, a2=1, a3=-1, a4=-5, a5=-13
Riemann Integral
Calculation using advanced Riemann functions is also possible.
Integration with Casio's Online Visualization Service
Compatibility with ClassPad.net, a convenient online service for classrooms equipped with ICT tools, has been enhanced.
The service can be accessed by scanning QR codes displayed on the calculator screen.
