Exploring Slope, Including a Study of Parallel and Perpendicular Lines
This activity contains 4 problems. The first 2 allow the students to notice relationships of slopes and y-intercepts to the location of lines. The second 2 problems help the students find the relationships between the slopes of parallel and perpendicular lines.https://education.ti.com/en/activity/detail/activity-with-slope-including-a-study-of-parallel-and-perpendicular-lines
Slopes with Starburst

Here's Looking At Euclid
Students first use the familiar prime factorization method to calculate the GCD and LCM of two numbers. Second, they apply Euclid’s algorithm, an iterative process for finding the GCD, in conjunction with a formula for the LCM given the GCD. In order to use the algorithm, they must first grasp th...https://education.ti.com/en/activity/detail/heres-looking-at-euclid
Area of the Missing Square

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
Interior & Exterior Angles of a Triangle
In this activity, students will measure interior and exterior angles of a triangle and make conjectures about their relationships.https://education.ti.com/en/activity/detail/interior--exterior-angles-of-a-triangle
Constructing Similar Triangles
Students investigate three different methods of constructing similar triangles.https://education.ti.com/en/activity/detail/constructing-similar-triangles
Points on a Perpendicular Bisector
Students will explore the relationship between a line segment and its perpendicular bisector. The concept of a point that is equidistant from two points is illustrated.https://education.ti.com/en/activity/detail/points-on-a-perpendicular-bisector
Midpoint Quadrilateral
This problem presents an opportunity for students to think about properties of quadrilaterals, and also to work on confirming observations through geometric reasoning. If your state has adopted the Common Core State Standards, this alignment might be helpful: Geometry: Prove Geometric Theorems G....https://education.ti.com/en/activity/detail/midpoint-quadrilateral
Application of a Circle: Angles and Arcs
