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

(CAS and non-CAS) allows “Plug N Play” with data collection devices

To begin you simply open a new document and add a blank notes page

Next, connect the CBR2, or Vernier probe, and an Auto Launch window appears.

Data Collection Console Once you select the type of page to

collect data onto, a split screen appears with the data collection console at the bottom

The data collection console controls the beginning and end of data collection

To change the frequency and duration of the data collection use the Experiment menu

To retry the data collection use the Data menu

The data collected is stored into variables dc01.time, dc01.dist1, dcc01.vel1 and dc01.acc1

Linear Data Modeling Demo The Nspire teacher

edition allows you to model data collection and linear modeling

You will need a mini-USB adapter available from Vernier

Lets see a demo ….

Experiments to Gather Data for Modeling:Linear Data Walk at a

constant rate Others?

Quadratic Data Ball bounce Roll a can up

a ramp Pillow toss Others?

Sinusoidal DataPendulumWalk arounda hula-hoopWeightedSpringsOthers?

It’s Your Turn … Form a group of 3 or 4. Your group must have members with at

least two different coloured poker chips Assign roles (Operator, Tech Support, Coach) Your group will complete all three activities:

Modeling Linear Data (Violet sheet) Modeling Quadratic Data (Light green sheet) Modeling Sinusoidal Data (Buff coloured sheet)

For extra support refer to: Data Collection with TI Nspire (Bright Green sheet) Manually Manipulating Functions on TI-Nspire (Pink Sheet)

Vernier Data Probes for Nspire Vernier offers four products for data collection

EZ-Temp Probe (connects to Handheld and collects real time temperatures), P/N EZ-TMP, $59

Go-Link (connect CBL2 probes to PC), P/N GO-LINK, $85

Easy Link (connect CBL2 probes to Nspire), P/N EX-LINK, $89

Mini USB Adapter (Connect EZ-Temp or CBR2 to PC), P/N MINI-USB, $7.50

Visit the Vernier booth for more information

Is it a Coincidence? Texas Instrument colours

and Team Canada’s colours are the same!!

P.S.: Yes, colour is spelled correctly
