Using a dynamic manipulative, students will have a visual for adding and subtracting integers.https://education.ti.com/en/activity/detail/hot-air-balloon_1
Hot Wheel Lab
In this activity, students will gather data that compares the slope of a hot wheel ramp to the distance the car travels. They will then graph, draw a line of best fit and write an equation for their data.https://education.ti.com/en/activity/detail/hot-wheel-lab
Area of Rectangles with Fixed Perimeter
The students will construct several rectangles with different dimensions, all having the same perimeter. The area of each rectangle is then computed and plotted against the width of each rectangle. The students will discover that the area is a quadratic function of the width. They will also dis...https://education.ti.com/en/activity/detail/area-of-rectangles-with-fixed-perimeter
Multiplicity of Zeros of Functions
In this activity for the TI-84 Plus CE Family, students will utilize graphs and equations of polynomial functions to determine the zeros of the functions and whether the functions cross the x-axis or is tangent to the x-axis at the zeros.https://education.ti.com/en/activity/detail/multiplicity-of-zeros-of-functions_1
Arithmetic Sequences & Series
Students use formulas to find the differences of the consecutive terms, plot a scatter plot of each sequence, and determine that sequences with common differences (called arithmetic sequences) have scatter plots whose points form a straight line.https://education.ti.com/en/activity/detail/arithmetic-sequences--series_1
Arc length and Area of Sectors
This is an introduction to finding the arc length and area of sectors of circles. Students should have the formulas for Circumference and Area of circles.https://education.ti.com/en/activity/detail/arc-length-and-area-of-sectors
The Amazing Race: Algebra Edition
This is a full lesson, and the guided practice section utilizes the Navigator system. The independent practice is the game The Amazing Race (explained in the PDF).https://education.ti.com/en/activity/detail/the-amazing-race--algebra-edition
Hide and Seek on the Coordinate Plane
The activity is designed as an introduction to the activity center on TI-Navigator™. Prior to the activity students should have covered graphing points on the coordinate plane, adding, subtracting, multiplying and dividing integers, as well as absolute value and comparing and ordering integers.https://education.ti.com/en/activity/detail/hide-and-seek-on-the-coordinate-plane
Exploring Cavalieri's Principle
Students explore Cavalieri's Principle for cross sectional area and volume.https://education.ti.com/en/activity/detail/exploring-cavalieris-principle
Shortest Distance Problem
