Investigation of Similar Rectangles
This activity shows how the ratios of perimeters and the ratios of areas of similar rectangles compare to the similarity ratios.https://education.ti.com/en/activity/detail/investigation-of-similar-rectangles
Inscribed Angles
Students use animation to discover that the measure of an inscribed angle is half the measure of its intercepted arc, that two angles that intercept the same, or congruent, arcs are congruent, and that an angle inscribed in a semi-circle is a right angle. They then discover that the opposite angl...https://education.ti.com/en/activity/detail/inscribed-angles_1
Intersecting the Solutions
In this teacher-led activity, students will learn to solve systems of equations graphically. They will learn the relationship between the algebraic and graphical solutions and create equations that draw upon this connection.https://education.ti.com/en/activity/detail/intersecting-the-solutions
It's a Parallelogram, You Say?
Students represent complex numbers in the complex plane as points or vectors and display the sum and difference of two complex numbers as diagonals of the parallelograms they define.https://education.ti.com/en/activity/detail/its-a-parallelogram-you-say_1
It's Getting Hot in Here
In this lesson, students will manipulate greenhouse gases to gather data on global temperature.https://education.ti.com/en/activity/detail/its-getting-hot-in-here
Intercepts, Zeros, Roots, Factors, & Solutions
During the activity, students will use the CALCULATE functions, POLYSMLT, and the graphing capabilities of their grapher to analyze the relationship between, x-intercepts, zeros, roots, factors, and solutions of polynomial functions/equations.https://education.ti.com/en/activity/detail/intercepts-zeros-roots-factors--solutions
Inscribing a Circle in a Triangle
In this activity, students bisect the angles of a triangle and find the incenter of the triangle. They find the distance from the incenter to the side of the triangle and use it as radius. With the incenter as the center, they inscribe a circle in a triangle. NCTM Geometry Standard covered: Anal...https://education.ti.com/en/activity/detail/inscribing-a-circle-in-a-triangle
