Today was released a new version of the add-in Algy 2 (previously tested
here) for Classpad II.
For those who still do not know, Algy2 is an application that is able to pinpoint any line of working (in resolution of equations, inequalities...) that contains an error. This application encourages experimentation and perseverance with symbolic manipulation (algebra).
It isn't free but it is inexpensive - $8 for a single copy, $120 for a school license and $150 for a school extended license which permits the software to be installed on all school and home computers of students and teachers.
There is a free trial version, but it doesn't have all of the features of the full version.
Below is a screenshot of the new version for classpad 400 and other of the version for classpad 300/300:
Even if you do not have a classpad 400 you can test the new version on
classpad II emulator. You just need copy the .C2A program to Classpad Manager Home Folder. Is something like:
C:\Users\USERNAME\Documents\CASIO\ClassPad Manager for ClassPad II
