4 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 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.
