Application of Slopes
Students will apply the concept of slope to a real-world problem about building a staircase. They will use the slope ratio, vertical change over horizontal change, to find the slope of staircase. Then, students will recognize how a positive or negative slope applies in a real-world situation.https://education.ti.com/en/activity/detail/application-of-slopes

Families of Rectangles
Students create a family of similar rectangles and then write the equation of the curve that will connect the upper-right vertex of each rectangle. Students will then create a family of rectangles that have the same area and will write the equation of the curve that connects the upper-right verti...https://education.ti.com/en/activity/detail/families-of-rectangles
Triangles and Slope - Is the Triangle Possible?
Students will construct triangles that match specific criteria. If it is possible to construct the triangle, the students have to construct the triangle and state the slope of each side. If the triangle is impossible to construct, the students must write a detailed explanation as to why it is im...https://education.ti.com/en/activity/detail/triangles-and-slope--is-the-triangle-possible
The "Great Pyramid" - Rate of Change
Students will explore different rates of change. Using the TI-Nspire students will be expected to make predictions based upon information that a Pharaoh has given. Students will explore points in a scatter plot of time and height on the building of a pyramid in ancient times. They will calcula...https://education.ti.com/en/activity/detail/the-great-pyramid--rate-of-change
Slopes with Starburst
Students will use Starburst to conduct an experiment that analyzes slope. The data will be entered into TI-Nspire and evaluated. Students explore concepts such as flat/steeper slopes and constant versus varied slope. Students also simulate distance versus time graphs using meter sticks and hot...https://education.ti.com/en/activity/detail/slopes-with-starburst
Rectangles and Parabolas
Students will tackle a traditional problem from the Algebra I curriculum geometrically, numerically, graphically, and algebraically: Sixty feet of fencing is purchased for the grounds crew to fence off a rectangular portion of property for a garden. The owner has made it perfectly clear that h...https://education.ti.com/en/activity/detail/rectangles-and-parabolas

Sums of Sequences
In this activity, students will develop formulas for the sum of arithmetic and geometric sequences. Students will then find the sum of sequences using the formulas developed.https://education.ti.com/en/activity/detail/sums-of-sequences_1
Recursive Sequences
In this activity, students will use the sequence mode of the graphing calculator to generate recursive sequences and then examine the values. They will also write recursive sequence formulas for given sequences.https://education.ti.com/en/activity/detail/recursive-sequences_1
Area of the Missing Square
In this activity, students will be introduced to an area model for representing a quadratic equation. Students will explore the relationship between the value of b and c, in y = x2 + bx + c, form of the quadratic equation. The relationship will be examined with integer and non-integer values in o...https://education.ti.com/en/activity/detail/area-of-the-missing-square_1
Connecting Algebra 2 to Statistics
Once students learn how to solve exponential and logarithmic equations, the students can take data and decide if an appropriate model is exponential. This activity will require students to create scatterplots and to have the knowlegde of the relationship being linear or nonlinear. This activity...https://education.ti.com/en/activity/detail/connecting-algebra-2-to-statistics
Once and For All...Absolutely
The activity is designed to be a lesson in solving absolute value inequalities. The intent is to distinguish the kinds of solutions that absolute value inequalities have and the forms of stating the solutions. More importantly the activity considers two methods of solutions: a graphing method and...https://education.ti.com/en/activity/detail/once-and-for-all---absolutely
The Open Box: An Exploration of Maximum Volume
The students will solve the problem of finding the maximum volume of a box cut from an 18 x 24 cm peice of paper in several ways. The student will actually cut out and form several different boxes. The student will fill the boxes with "starburst" candies and then use their TI-Nspires to analyze...https://education.ti.com/en/activity/detail/the-open-box-an-exploration-of-maximum-volume
Conditional Statements
In this activity, students construct examples of conditional statements such as parallel and perpendicular lines. After completing the conditional statement, they will write the converse, inverse, and contrapositive and determine if each is true.https://education.ti.com/en/activity/detail/conditional-statements
