NUMB3RS - Season 3 - "Killer Chat" - The Perfect House
The FBI found three bodies in different unoccupied houses, all for sale. Because the victims are completely unrelated, Charlie decides that profiling the houses might reveal a distinct pattern to find out where the killer will strike next. By using a Multi-Attribute Compositional Model, the house...https://education.ti.com/en/activity/detail/numb3rs--season-3--killer-chat--the-perfect-house
Median and Interquartile Range
In this lesson students are introduced to the median and, by taking the median of each half of the data, to quartiles and the interquartile rangehttps://education.ti.com/en/activity/detail/medians-and-iqrs-bc

Students explore the use of manipulatives to conduct simple geometry and measurement activities.https://education.ti.com/en/activity/detail/measurement-and-geometry
Comparing Distributions of Univariate Data
Students compare univariate data distributions using statistical concepts like boxplots, stemplots, and histograms.https://education.ti.com/en/activity/detail/comparing-distributions-of-univariate-data
Mean As a Fair Share
This lesson introduces students to mean as a way to describe the center of a set of data. Often called the average, the mean can also be visualized as “leveling out” the data in the sense of “fair share”.https://education.ti.com/en/activity/detail/mean-as-a-fair-share-bc
Mean As A Balance Point
In this lesson, students calculate deviations from the mean, how far each value is above or below the mean. Students also focus on the balance point of a distribution, where the sum of the absolute deviations below the mean is equal to the sum of the absolute deviations above the mean.https://education.ti.com/en/activity/detail/mean-as-a-balance-point-bc
Box Plots
In this lesson, students plot the two extreme values (minimum and maximum), the lower quartile (LQ), upper quartile (UQ), and the median (a five-number summary) on a number line to create a graph called is a box plot.https://education.ti.com/en/activity/detail/box-plots-bc
Special Cases of Normally Distributed Data
Students perform single and two-sample t procedures to investigate special cases of normally distributed data. They explore inference for a least-square regression line, including the confidence interval.https://education.ti.com/en/activity/detail/special-cases-of-normally-distributed-data
Similarity and Dilations
Students will discover properties of similar figures using the TI-89 and CABRI Geometry II to use dilations to dynamically manipulate figures. (Topic - Similar Figures and the Role of Dilations)https://education.ti.com/en/activity/detail/similarity-and-dilations
What's the Trig?
Students will be introduced to right triangle trigonometry. They will use the TI-89 and Geometer's Sketchpad to construct a right triangle and calculate sin, cosine, and tangent of various acute angles. (Topic - Right Triangle Trigonometry)https://education.ti.com/en/activity/detail/whats-the-trig
Parallel or Perpendicular-What's Your Inclination?
This activity has students discover the relationship between parallel and perpendicular lines and their slopes. After constructing these objects using CABRI Geometry II for the TI-89, slopes are measured. (Topic - parallel and perpendicular lines)https://education.ti.com/en/activity/detail/parallel-or-perpendicularwhats-your-inclination
Parallelograms - Discovering Their Properties
Students use the TI-89 with CABRI™ Geometry to discover properties of parallelograms. They will construct a figure and use the definition to disvoer the figure is a parallelogram. (Topic - parallelograms)https://education.ti.com/en/activity/detail/parallelograms--discovering-their-properties
Properties of Parallelograms
In this activity, you will construct the geometric object by following the instructions below, and then answer the questions about the object.https://education.ti.com/en/activity/detail/properties-of-parallelograms_4
Proportional Flag
Students will use the concepts of similarity to create a scale drawing of the national flag, that is large enough to cover most of a football field.https://education.ti.com/en/activity/detail/proportional-flag
What's the Angle?
Students discover properties of interior and exterior angles of convex polygons using the TI-89 and Geometer's Sketchpad. (Topic - Interior and Exterior Angles of Convex Polygons)https://education.ti.com/en/activity/detail/whats-the-angle
What's the Spin?
Students discover properties of rotations using the TI-89 and CABRI Geometry II by rotating a triangle around a point and through a specified angle. They will discover the definition of a rotation.
