Returns on a Share of Stock
In this activity, students will determine the internal rate of return of the cashflows associated with the stock purchase, dividends, and sale. They will carry out explorations by varying the selling price of the stock and examining the impact on the rate of return.https://education.ti.com/en/activity/detail/returns-on-a-share-of-stock
Investigating Segments in a Triangle
In this activity, students investigate the midsegments of a triangle as in the previous activity. They continue to explore these segments and extend their understanding of the relationships that exist between the slopes of lines containing the segments. NCTM Geometry Standard covered: Analyze ch...https://education.ti.com/en/activity/detail/investigating-segments-in-a-triangle
Constructing Quadrilaterals
In this activity, students will construct different types of quadrilaterals from the quadrilateral hierarchy. This activity asks for constructions based on a minimal definition of the quadrilateral. The activity will reinforce the difference between a construction and a drawing.https://education.ti.com/en/activity/detail/constructing-quadrilaterals
NUMB3RS - Season 2 -"Hot Shot" - A Stab in the Dark
In "Hot Shot," two victims of a possible serial criminal are found. Charlie uses kernel density estimation as a method for predicting a change in behavior to indicate a connection between the victims and the criminal.https://education.ti.com/en/activity/detail/numb3rs--season-2-hot-shot--a-stab-in-the-dark
Watching Your Weight - TI-83
In this activity, students examine how moving a weight up along a board affects the downward force on the board. They explore how children with different weights can be balanced on a seesaw.https://education.ti.com/en/activity/detail/watching-your-weight--ti83
How Many Drivers? Investigate the Slope-Intercept Form of a Line
In this activity, students will be introduced to the slope-intercept form of a linear equation. They will recognize the effects of changes in the slope and y-intercept on the graph of a line. Students will use the Transformation Graphing application to find an approximate linear model of the actu...https://education.ti.com/en/activity/detail/how-many-drivers-investigate-the-slopeintercept-form-of-a-line
Statistics for Math B
Students will determine the mean, median, mode and standard deviation of collected data. They will make a frequency histogram of the grouped data, both on graph paper, and on the TI 83+.https://education.ti.com/en/activity/detail/statistics-for-math-b
One of the Many Ways
Students graph polynomials to determine the value and number of zeros for a given polynomial.https://education.ti.com/en/activity/detail/one-of-the-many-ways
Linear Equations for Which the Difference between the Coordinates is Constant
This activity allows students to explore situations in which points with a constant difference between coordinates are graphed. With TI-Navigator?s display, students can determine that an oblique line is formed from such points. This oblique line always has intercepts equal to the constant diff...https://education.ti.com/en/activity/detail/linear-equations-for-which-the-difference-between-the-coordinates-is-constant
Asymptotes & Zeros
Students relate the graph of a rational function to the graphs of the polynomial functions of its numerator and denominator. Students graph these polynomials one at a time and identify their y-intercepts and zeros. Using the handheld's manual manipulation functions, students can manipulate the gr...https://education.ti.com/en/activity/detail/asymptotes--zeros_1
The Quest for Roots of Higher Order Equations
Students learn how to approximate the roots of any polynomial equation of any order by first using tables, and then by tracing along the graph to the point where the curve intersectshttps://education.ti.com/en/activity/detail/the-quest-for-roots-of-higher-order-equations
Absolutely Wonderful
