Function Modeling The Ontario secondary Mathematics curriculum has a function modeling theme that runs from grades 9 to 12 Nspire makes function modeling accessible to every student using only handhelds and CBR2’s Linear modeling in grade 9 Quadratic modeling in grade 10 Periodic (Sinusoidal) modeling in grade 11 Collecting data improves student engagement and comprehension
Auto Launch Window Since OS v1.6, Nspire allows “Plug N Play” with data collection devices To begin you simply open a new document and add a blank notes page Connect the CBR2, or Vernier probe, and an Auto Launch window appears…

Nspire CAS Teacher Edition Software This software allows you to demo data collection You will need a mini- USB adapter Lets see a demo ….
Data Collection using the CBR2 Now it’s your turn. Form teams of three with a variety of experience levels in your team Each team uses one handheld, one CBR2 and tools to collect data You will do three activities in a carousel: Collect and model linear data Collect and model quadratic data Collect and model periodic data If you need help refer to the data collection handout
