Points on a Line
Develop an understanding of the slope of a line.https://education.ti.com/en/activity/detail/points-on-a-line_1
Investigating the Angles of a Triangle
The following will find the sum of the interior angles of a triangle and the sum of the remote interior angles of a triangle. Students can then change the type of triangle. The student will see that the sum of the interior angles is always 180 degrees. Also, the student will see that the sum of t...https://education.ti.com/en/activity/detail/investigating-the-angles-of-a-triangle
Factoring Special Cases
Students explore geometric proofs for two factoring rules: a2 + 2ab + b2 = (a + b)2 and x2 – a2 = (x – a)(x + a). Given a set of shapes whose combined areas represent the left-hand expression, they manipulate them to create rectangles whose areas are equal to the right-hand expression.https://education.ti.com/en/activity/detail/factoring-special-cases_1
Variables and Expressions
Change the value of x on a number line and see the effect on an algebraic expression.https://education.ti.com/en/activity/detail/variables-and-expressions
Interior Angles of Regular Polygons
Explore the interior angles of regular polygons by dividing the polygons into triangles.https://education.ti.com/en/activity/detail/interior-angles-of-regular-polygons
