Equations of Circles
In this activity, students will explore the relationship among the location of the center of the circle, the radius of a circle, and the equation of a circle in a plane. They will also investigate the relationship between the points inside, on, and outside a circle, and the equation of the circle.https://education.ti.com/en/activity/detail/equations-of-circles_1
Math TODAY: Wing Tabs Save Fuel
Using the USA TODAY® Infograph, 'Wing Tabs Save Fuel,' ratios and proportions will be used to explore the concept of similarity between a drawing/model and the actual dimensions. The effects of dilation (size change) on an image and pre-image will also be explored. In addition, students will look...https://education.ti.com/en/activity/detail/math-today-wing-tabs-save-fuel
Discovering the Quadrilateral Properties
This activity will use Cabri™ Jr. to allow students' the ability to discover all of the properties of each quadrilateral, rather than simply copying them out of a textbook.https://education.ti.com/en/activity/detail/discovering-the-quadrilateral-properties
Isosceles Triangle
In this activity, students construct isosceles and equilateral triangles. They discover that if two sides of a triangle are congruent, then the angles opposite them are congruent. They understand that an equilateral triangle is also equiangular.https://education.ti.com/en/activity/detail/isosceles-triangle
