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
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
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
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
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
