Stay Tuned Lab Sound Waveform Models
In this activity, students' will record the sound waveform of a tuning fork and analyze the waveform to determine frequency, period and amplitude information. They will model the waveform using trigonometric functions. This activity has been modified for TI-Nspire with the data in the activity file.https://education.ti.com/en/activity/detail/stay-tuned-lab-sound-waveform-models
Transitions
Students will explore converting rectangular equations to polar form and vice versa. Familiar trigonometric identities and circle relationships are applied in making the conversions.https://education.ti.com/en/activity/detail/transitions_1
Logarithmic Transformations of Data
This lesson involves three real-world data sets in which the relationship between each pair of variables is non-linear. Students will be asked to describe the original relationship between each pair of variables, and observe how each transformation is used to achieve a linear relationship.https://education.ti.com/en/activity/detail/logarithmic-transformations-of-data
Nonlinear Systems of Equations
Students will be introduced to nonlinear systems of equations. It begins by allowing students to move figures around the screen to see ways certain types of graphs (linear/conic and conic/conic) can intersect each other and how many possible intersection points are possible. The activity conclude...https://education.ti.com/en/activity/detail/nonlinear-systems-of-equations
Accelerated Returns
Students compare periodic and continuous compounding and apply continuous compounding to a variety of problem situations.https://education.ti.com/en/activity/detail/accelerated-returns

Operation Rules
In this short activity, students use interactive pages with sliders to determine rules for different combinations of adding and subtracting positive and negative numbers such as adding two negative numbers.https://education.ti.com/en/activity/detail/operation-rules
One Sided Limits
Students will be given piecewise functions and asked to evaluate both the left-hand limit and the right-hand limit of the function as x approaches a given number, c. Using sliders, students will estimate the value of the missing variable that makes the left-hand limit and the right-hand limit equal.https://education.ti.com/en/activity/detail/one-sided-limits_1
Alternating Series
Students will use the capabilities of their handhelds to find limits and compare two series to determine if the alternating series converges or diverges. Then students will approximate the sum of an alternating series by using a table to find partial sums and using the Alternating Series Remainde...https://education.ti.com/en/activity/detail/alternating-series_1
Application of Area Formulas
Students will be able to find the area of polygons by breaking a polygon into familiar shapes, such as triangles, rectangles, and trapezoids.https://education.ti.com/en/activity/detail/application-of-area-formulas
