Got an equilateral triangle? with Cabri Jr.
Using the Compass tool in Cabri Jr., students will construct an equilateral triangle, and check the length of each side. When a vertices is moved using the Alpha hand, the triangle remains equilateral.https://education.ti.com/en/activity/detail/got-an-equilateral-triangle---with-cabri-jr
Scientific Operations
This StudyCards™ set is a guided discovery of the four operations with numbers in scientific notation. Use with Foundations for College Mathematics, Ch. 1-4.https://education.ti.com/en/activity/detail/scientific-operations
Approximation of Pi
Students will measure the circumference and diameter of a variety of different circles. They will graph the class' values of (d,c) on the coordinate plane and use linear regression to approximate pi.https://education.ti.com/en/activity/detail/approximation-of-pi
Solving Systems of Equations
This activity can be used as a self assessment or as a small quiz over solving systems of linear equations. Requires knowledge of substitution and elimination.https://education.ti.com/en/activity/detail/solving-systems-of-equations
Solving Trigonometric Equations
Students represent and analyze mathematical situations and structures using algebraic symbols.https://education.ti.com/en/activity/detail/solving-trigonometric-equations
What Goes Around Comes Around - But Can You Measure It? (Perimeter, Area, and Volume)
Students find the area and the perimeter for several geometric shapes. They also determine the surface area and volume of spheres.https://education.ti.com/en/activity/detail/what-goes-around-comes-around--but-can-you-measure-it-perimeter-area-and-volume
Eating Out
Students examine data and make graphs to represent the data. They interpret the data and answer questions. They also learn to calculate percentages and angle measures.https://education.ti.com/en/activity/detail/eating-out
What Goes Up Must Come Down
In this activity, students use the calculator to solve quadratic equations. They use the quadratic formula to determine the vertex and the x-intercepts of the graph of a quadratic function.https://education.ti.com/en/activity/detail/what-goes-up-must-come-down
How Fast for Whiplash? Going with the Flow
Students recognize direct variation as a rate of change and apply it in problem situations. They also use average rates of change to make decisions in problem situations.https://education.ti.com/en/activity/detail/how-fast-for-whiplash-going-with-the-flow
