Once and For All...Absolutely
The activity is designed to be a lesson in solving absolute value inequalities. The intent is to distinguish the kinds of solutions that absolute value inequalities have and the forms of stating the solutions. More importantly the activity considers two methods of solutions: a graphing method and...https://education.ti.com/en/activity/detail/once-and-for-all---absolutely
Conditional Statements
In this activity, students construct examples of conditional statements such as parallel and perpendicular lines. After completing the conditional statement, they will write the converse, inverse, and contrapositive and determine if each is true.https://education.ti.com/en/activity/detail/conditional-statements
Midsegments of Triangles
In this activity, students will explore the properties of the midsegment, a segment that connects the midpoints of two sides of a triangle. First, students will construct and investigate one midsegment and the relationship of the new small triangle to the original triangle. Then, all three midseg...https://education.ti.com/en/activity/detail/midsegments-of-triangles_1
