TI-Navigator Systems come in 10-user and 30-user configurations. There is also a 10-User add-on option for supporting different class sizes.

TI-Nspire Handhelds
TI-Navigator Systems do not include the TI-Nspire handhelds. We recommend purchasing teacher packs of 10 handhelds, which include a docking station for keeping the handhelds charged. There are two handheld models to choose from; both will work with your Navigator system.
     Numeric: TI-Nspire CX II Handheld (TI-NSCX2-TPK)
     CAS: TI-Nspire CX II CAS Handheld (TI-NSCXCAS2-TPK)

Class-size up to 10 Students
     TI-Nspire CX Navigator System (TI-NAV-CX10)
     One (1) TI-Nspire Teacher Pack of 10 Handhelds (Numeric or CAS)

Class-size 10 to 20 Students
     TI-Nspire CX Navigator System (TI-NAV-CX10)
     TI-Nspire CX 10-User Navigator System Add-On (TI-NAV-10ADDON)
     Two (2) TI-Nspire Teacher Packs of 10 Handhelds (Numeric and/or CAS)

Class-size 20 to 30 Students
     TI-Nspire CX Navigator System (TI-NAV-CX30)
     Three (3) TI-Nspire Teacher Packs of 10 Handhelds (Numeric and/or CAS)

Class-size 30 to 40 Students
     TI-Nspire CX Navigator System (TI-NAV-CX30)
     TI-Nspire CX 10-User Navigator System Add-On (TI-NAV-10ADDON)
     Four (4) TI-Nspire Teacher Packs of 10 Handhelds (Numeric and/or CAS)
     40 is the largest number of handhelds a TI Navigator system can support.

Support for two classes with 10 to 20 Students
While you can purchase two of what is listed above for 10 to 20 student classrooms, the configuration below is a less expensive alternative. In this case, 10 of the network adapters that come with the 30-user system will be used with the 10-user system to create two 20-user systems.
     TI-Nspire CX Navigator System (TI-NAV-CX30)
     TI-Nspire CX Navigator System (TI-NAV-CX10)
     Four (4) TI-Nspire Teacher Packs of 10 Handhelds (Numeric and/or CAS)
     Network adapters are not required to be used with the Navigator system from which they came. They can be used with a different system if needed. Does the TI-Nspire CX wireless adapter only work with the TI-Navigator system from which it came?
