Proofs Packet - Intro to Geometry Proofs Notes Packet with Activities
Proofs are a very difficult topic for most students to grab. Starting off with some basic proofs after some basic geometry concepts have been introduced develops a good solid foundation. This packet gives an introduction to proofs, a good mix of the basic theorems, properties, postulates and theorems that are used in proofs. Students can follow the same structure to organize new theorems, postulates and definitions in their notebooks as the year goes on - or you can buy the next extended vers

Error Analysis: Parallel Lines Cut By A Transversal
Error Analysis Tasks are a great way to help students learn to analyze work for mistakes and make corrections. Over time, students become more comfortable with the process and learn how to check their own work. Students are also able to work on the justification of their answers. This assignment requires zero prep as well! One way to implement this assignment is to have students work with a partner. Students take turns explaining to their partners where the mistake is located and how to correct
