The eActivity and Presentation Applications promote manipulation, exploration and sharing of solutions throughout the whole classroom. This encourages each student to increase their interest and ability in math. 1. You can create and prepare your own original activities for the class with eActivity. 2. Students can work on a problem at their own pace. 3. Students can try out various approaches to solving a problem by themselves. 4. It enables texts, expressions, figures and graphs to be presented on the screen of the ClassPad 300. It is an innovative electronic educational material that can be freely created and learned on the ClassPad 300. You can enjoy all the benefits of the useful functions of the ClassPad 300 with eActivity. eActivity is effective not only in the classroom. It is also suitable for home study, since the student can change the given mathematical expressions or numerical values easily, and practice at home with problems they have made themselves. Students can make presentations of the results of what they have learned in class or at home. When making a presentation, it makes it even more convenient if you use the Presentation Application and RM-ClassPad. The Presentation function provides storage of data displayed on the LCD screen as image data, and displays it in a slideshow format. It is a very effective function for presenting the results of group study or home study. The class can be made even more effective if you combine the RM-ClassPad to project the presentation via OHP. The RM-ClassPad (SET) lets you send data from a remote control unit to an OHP projection unit for projection onto an OHP screen.
