This article justifies classifying the TI-Nspire CAS Touchpad as a mobile device for grades 8-16 mathematics classrooms equipped with a Navigator system. The 2010 Horizon Report: K-12 indicates virtually every secondary school aged child has some sort of mobile device. Yet, many school policies ban the use of mobile devices, preventing students from using these devices in an educational setting. Further, some teachers have been slow to adopt and use mobile devices to advance the educational setting of their classroom to a 21st century classroom. A classroom equipped with wireless Navigator technology and students equipped with Nspire handhelds presents an engaging 21st century mathematics classroom for all learners. These classrooms present a happy-medium wireless communication setup that prevents students from communicating with each other or browsing the web. Students can instantly communicate with the teacher and vice-verse. Students stay on task while using a mobile device.
