Technology tools such as the TI-84 Plus family of graphing calculators can be a powerful support for mathematical modeling activities. It opens up opportunities for student to compare models graphically, to use regression for making and testing predictions, and to simulate processes that would be difficult or impossible to do without technology.

This set of activities seeks to illustrate how the TI-Nspire™ CX family of graphing calculators could be used to effectively support the vision of the GAIMME document. The document “Guidelines for Assessment & Instruction in Mathematical Modeling Education” (GAIMME) was published in 2016 by the Consortium for Mathematics and its Applications (COMAP) and the Society for Industrial and Applied Mathematics (SIAM). GAIMME is a rich resource for teachers at all levels K–16, and it provides valuable advice for making modeling an integral part of mathematics instruction.


Featured Activities

Modeling CO2 Levels

This lesson provides an opportunity to engage students with data that is relevant to contemporary discussions of climate change. Students will compare multiple box plots of the data across years, analyze scatter plots and fit models to the data.

Modeling QB Passing Rates

This lesson uses the measures commonly collected for football quarterbacks and provides an opportunity for students to create their own quarterback rating models. As a result, students will model a contextual situation mathematically and use the model to answer a question.
