Triangle Midsegment Theorem
Students will use Cabri Jr. to discover that the midsegment of a triangle is parallel to the third side and half the length of the third side.https://education.ti.com/en/activity/detail/triangle-midsegment-theorem
Ryan's Puppy Problem
This problem can be used in Geometry of Algebra. Ryan desires to build a rectangluar fence to keep his puppy in. What shape should he use if he has 8 meters of fencing?https://education.ti.com/en/activity/detail/ryans-puppy-problem

Reflections
This activity will let students understand the concept of reflection.https://education.ti.com/en/activity/detail/reflections
Drawing a Line Tangent to a Circle
Students use the drawing and measurement tools of Cabri™ Jr. to draw a line tangent to a circle. NCTM Geometry Standard covered: Analyze characteristics and properties of 2- and 3-dimensional geometric shapes and develop mathematical arguments about geometric relationships.https://education.ti.com/en/activity/detail/drawing-a-line-tangent-to-a-circle
Special Parallelograms
In this activity, students will study special types of parallelograms like rhombus and rectangle, and investigate properties related to their diagonals.https://education.ti.com/en/activity/detail/special-parallelograms_1
STAAR / EOC: Dilations in the Coordinate Plane Using Cabri Jr.
Students will use the dynamic geometry tool of Cabri Jr. to see the relationships between ratios of distances and dilations.https://education.ti.com/en/activity/detail/eoc-dilations-in-the-coordinate-plane-using-cabri-jr
Experimentally Calculating Pi
Because the diameter of a circle is related to the circumference of a circle, we can find this constant relationship by measuring several lids and fitting a regression line to the data. The slope of this line is pi. This is a great activity to allow students to discover that Pi is the relations...https://education.ti.com/en/activity/detail/experimentally-calculating-pi
NUMB3RS - Season 2 - "Double Down" - A Bit of Basic Blackjack
In "Double Down," three students are tied up in a money-laundering scheme involving money won in the card game blackjack. In this activity, we discuss a simplified version of blackjack and analyze the probability of winning in various situations. Because cards are drawn from the deck and not re...https://education.ti.com/en/activity/detail/numb3rs--season-2--double-down--a-bit-of-basic-blackjack

What Is Your Grade (Part 1)
In this activity, students will use the CellSheet Application and set up a spreadsheet. They will determine the mean of a set of values and find a minimum value to be added to a set of values to obtain a given mean.https://education.ti.com/en/activity/detail/what-is-your-grade-part-1
Testing Hypotheses (Means, Proportions, and Standard Deviations)
In this activity, students evaluate hypotheses.https://education.ti.com/en/activity/detail/testing-hypotheses-means-proportions-and-standard-deviations
NUMB3RS - Season 2 - "The Running Man" - The Eyes Have It
The FBI is investigating a robbery at the research facility of a large company. The FBI believes that the robbers were employees of the company, because they were able to bypass the iris recognition security scan and gain entrance. However, a security camera was able to capture a partial image of...https://education.ti.com/en/activity/detail/numb3rs--season-2--the-running-man--the-eyes-have-it
Survey Project
Students survey other students (numerical and non numerical data) and calculate measures of central tendency (if possible) of data and make regular box-an-whisker plots and outlier box-and-whisker plots to analyze the data.https://education.ti.com/en/activity/detail/survey-project
