NUMB3RS - Season 3 - "Longshot" - Expected Value
In "Longshot", a man is murdered after the horse he bet on won a race. A notebook filled with horse racing data and equations is found on the victim. Charlie finds that the equations were designed to pick the second place finisher. He explains that the racetrack uses a pari-mutuel betting system,...https://education.ti.com/en/activity/detail/numb3rs--season-3--longshot--expected-value
NUMB3RS - Season 3 - "Finders Keepers" - Barging In
In "Finders Keepers," the body of a diver is found in the ocean. The body is traced to a salvage barge that has a bloody handprint on it. After further investigation, it is discovered that the blood is not from the dead diver, but someone else murdered on the barge. In order to find the other vic...https://education.ti.com/en/activity/detail/numb3rs--season-3--finders-keepers--barging-in
Classifying Quadrilaterals
Students receive two Cabri Jr. files of quadrilaterals on a coordinate plane. They use their knowledge of quadrilaterals to give each one the most precise name. They may find the length and/or slope of the sides using the measuring tools of Cabri Jr. to assist in their classification.https://education.ti.com/en/activity/detail/classifying-quadrilaterals_1
Classifying Triangles by the Length of the Sides Using Cabri Jr.
This activity uses Cabri Jr. to classify triangles according to the length of their sides.https://education.ti.com/en/activity/detail/classifying-triangles-by-the-length-of-the-sides-using-cabri-jr
Identifying Types of Correlation from a Graph and Calculator
Students will identify different types of correlations graphically and by using the linear regression analysis obtained from a TI-84 Plus calculator. Students will also obtain and know the significance of a correlation coefficient as a result of this lesson.https://education.ti.com/en/activity/detail/identifying-types-of-correlation-from-a-graph-and-calculator
Investigating the Sine and Cosine Functions
Students use Cabri? Jr. to draw a circle and investigate the relationship between the coordinates of a point on the circle and sine and cosine of the angle whose terminal side passes through that point.
