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

Decimal Defender App
This App helps students practice multiplication and division with decimals in a fun environment. Students use this App to learn standard multiplication and division algorithms as well as understand topics such as scientific notation, the metric system, and more.https://education.ti.com/en/activity/detail/decimal-defender-app
Modeling Exponential Decay with a Look at Asymptotes
In this activity, students approximate exponential decay models by defining parameters A and B in the exponential equation y = abx. They identify non-zero asymptote form of an exponential function.https://education.ti.com/en/activity/detail/modeling-exponential-decay-with-a-look-at-asymptotes
More difficult factoring
To check sign placement for factoring of trinomials when the coefficient in front of the x square is greater than one and the signs are different.https://education.ti.com/en/activity/detail/more-difficult-factoring
Lets Gather Round the Circle
The students will measure the diameter and circumference of various round objects. They will discover the relationship between the circumference and diameter.https://education.ti.com/en/activity/detail/lets-gather-round-the-circle
Lines in the Plane
In this activity, students create a slope triangle and understand the concepts of slope and the equation of lines. They realize that slope is constant at all points along a fixed line. They also explore the slopes of parallel and perpendicular lines.https://education.ti.com/en/activity/detail/lines-in-the-plane
Pass the Ball
Students use mathematics to examine patterns that occur in a specific scenario and predict future events for the scenario. Data is collected on the time it takes to pass a ball. The students plot graphs, fit the data with a function rule, analyze proportional relationships, and make predictions.https://education.ti.com/en/activity/detail/pass-the-ball
