5 Inspire Students to Learn

ClassWiz is more than just a calculation tool — it's packed with features designed to deepen students' understanding of mathematical concepts.
Math Box and Spreadsheet help students enjoy learning math.

Math boxNEW

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.

Spreadsheet

The spreadsheet functions is useful for learning statistics, recursive formulas and various mathematics concepts.
Student can use easily real-world data even in the classroom and study statistical processing more effectively.

Recursion

The spreadsheet functions makes it possible to enter recursive formulas.

Sequence: a₁=2 and a_n+1 -2a_n-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.

6 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.
