The Conic Graphing Application provides enhanced conics functions to the already powerful TI-83 Plus and TI-84 Plus. Graph or trace circles, ellipses, hyperbolas, and parabolas and solve for the conic's characteristics. Present equations in function, parametric, or polar form.https://education.ti.com/en/activity/detail/getting-started-with-conic-graphing-app
So Many Zeros!
Students will explore standard and scientific notation representations of numbers. Students will also discuss the need for different representations of very large or small numbers, and they will see real-world examples of these representations.https://education.ti.com/en/activity/detail/so-many-zeros_1
Find the Square Root...
Students who understand the basic concept of square roots learn how to evaluate expressions and equations that have rational and irrational solutions. Students also explore solutions to equations and investigate the differences between exact and approximate solutions using the calculator.https://education.ti.com/en/activity/detail/find-the-square-root

Exploring Exponents
Students will investigate and describe negative and zero exponents on the base. Then, students will apply the properties of integer exponents to generate equivalent expressions.https://education.ti.com/en/activity/detail/exploring-exponents
Modeling Virus Spread
In this TI-Nspire activity, students will explore a simple introduction to the idea of logistic growth through an easily acted out simulation: spread of a virus through a population.https://education.ti.com/en/activity/detail/modeling-virus-spread
Modeling QB Passing Rates
This activity uses the measures commonly collected for football quarterbacks and provides an opportunity for students to create their own quarterback rating models.https://education.ti.com/en/activity/detail/modeling-qb-passing-rates
100 or Bust
Students explore the operations of addition and subtraction. They use estimation, a place value chart, and a calculator to place seven randomly generated numbers in the ones and tens position in a place-value chart to make a sum as close to 100 as possible.https://education.ti.com/en/activity/detail/100-or-bust
