Mathematics Exercise Series Thales’ Theorem
The worksheet features six progressively challenging exercises that cover various geometric configurations: Triangle Proportionality (Exercises 1, 2, 3, & 6): Students calculate missing side lengths and prove lines are parallel using both the basic theorem and its converse.Trapezoids and Tangents (Exercises 4 & 5): The series extends the theorem to complex figures like trapezoids and circles with common external tangents, requiring higher-level algebraic manipulation.Step-by-Step Solutions: A co

Special Angle Pairs, Parallel Lines Transversal - Group Practice Activity
This self-checking parallel lines and transversals group activity challenges high school geometry students to calculate special angle pair measures, while simultaneously reviewing the Algebra 1 skill of solving systems of linear equations. Each student works through 6 unique problems using angle relationships with parallel lines to write and solve linear equations (including systems), then compare answers with their group. When everyone solves correctly, all group members arrive at the same answ

Connected Visual Representations for Probability (Venn, Tree, 2-Way Tables, etc)
The visual connections between diagrams in Probability are shown in this 1 page document. After teaching AP Statistics for 5 years and seeing students solve problems using multiple methods, I searched to find these connections and help other teachers see the validity of different methods in the same problem (instead of "well you do this problem this way"). After finding nothing on the internet, I created it myself. Now teaching Geometry, every year I make students do a Binary Data Collection pro
