Matrix Transformation of Triangles
The symmetry of a trangle on the coordinate plane is discovered through the 2X2 matrix transformations.https://education.ti.com/en/activity/detail/matrix-transformation-of-triangles
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
Breakeven Analysis
In this activity, students perform breakeven analysis using the cost and revenue of an enterprise. They will determine the relationship between fixed and variable costs, profits, pricing policy, and the volume of output.https://education.ti.com/en/activity/detail/breakeven-analysis
Inverse Variation
Students explore the inverse variation function with a geometric representation (a rectangle with fixed area), a table of values, an algebraic expression, and a graph.https://education.ti.com/en/activity/detail/inverse-variation
Parabola Construction
Students construct parabolas using the focus and directrix definition. They also explore how the location of the focus with respect to the directrix affects the shape of the parabola.https://education.ti.com/en/activity/detail/parabola-construction
Greatest Area Activity
In this activity students will explore area as it compares to length of rectangles with a fixed perimeter by creating lists of the possible dimensions and the areas of these rectangles. Students will then graph a scatterplot of the data, find the quadratic regression, and explore the table of val...https://education.ti.com/en/activity/detail/greatest-area-activity_1
Operating on Matrices
Students learn how to add, subtract, and multiply matrices, as well as find the determinant and inverse of a matrix.https://education.ti.com/en/activity/detail/operating-on-matrices
Transformers (Matrices)
Students explore a special subset of the transformations of a square called the symmetry group. They also find inverses of each transformation in the symmetry group. They then delve deeper into the algebra behind transformations, connecting them with matrix multiplication. Last, students extrapol...https://education.ti.com/en/activity/detail/transformers-matrices
Distance and Midpoint Formulas
Self checking using the attached LearningCheck™ .edc file. These six questions, maybe used for class warmup, review, or checking for understanding.https://education.ti.com/en/activity/detail/distance-and-midpoint-formulas
Determining Area
Students use the area formula involving the determinant of a matrix.https://education.ti.com/en/activity/detail/determining-area_1
Who Needs Mixed Numbers?
Students divide and multiply mixed numbers and fractions in real-life examples relating to carpentry.https://education.ti.com/en/activity/detail/who-needs-mixed-numbers
Fencing the Dog Yard
Algebra 1 students investigate how the area of a dog yard changes based upon a fixed amount of fencing. The concepts presented are a nice introduction to working with quadratics.https://education.ti.com/en/activity/detail/fencing-the-dog-yard
Properties of an Ellipse
Students discover properties of an ellipse, such as the set of all points such that the sum of the distances from these points to two fixed points is constant.https://education.ti.com/en/activity/detail/properties-of-an-ellipse
The Dirty Dawg Salon
In this activity, students will work through a scenario of a business venture involving washing dogs. They will translate fixed and variable costs to a cost function and make a decision about how much to charge to wash per dog. When the break-even point is found, students must interpret it to ans...https://education.ti.com/en/activity/detail/the-dirty-dawg-salon
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
Guess My Slope
Students will estimate the slope of six lines. Students will then return to each line and use the measurement capabilities of the TI-nspire to find the actual slope of each line. Students will find the absolute value of the differences between their estimates and the actual slopes in order to d...https://education.ti.com/en/activity/detail/guess-my-slope
Trigonometric Patterns
Students will use the unit circle to examine patterns in the six trigonometric functions.https://education.ti.com/en/activity/detail/trigonometric-patterns
Trigonometric Patterns
Students use the unit circle to examine patterns in the six trigonometric functions.https://education.ti.com/en/activity/detail/trigonometric-patterns@84
Properties of an Ellipse
Students discover properties of an ellipse, such as the set of all points such that the sum of the distances from these points to two fixed points is constant.https://education.ti.com/en/activity/detail/properties-of-an-ellipse_1
Reduce It!
Students write augmented matrices for systems of equations and then solve the system by writing the augmented matrix in reduced row-echelon form.https://education.ti.com/en/activity/detail/reduce-it
Vernier - Acid Rain
Students use the pH sensor to measure changes in the pH when CO2 dissolves in water. They also study the changes in the pH when sulphuric acid is added to water and identify water bodies most likely to be affected by acid rain.https://education.ti.com/en/activity/detail/vernier--acid-rain
