Description
This PowerPoint is designed to serve as an introduction to writing proofs. It contains guided notes, examples and practice problems. This product is editable - feel free customize it to fit the needs of your classroom!
This product is geared towards stronger students, as it progresses quickly from fill-in-the-blank proofs to write-your-own proofs. If you are looking for a basic version geared towards weaker students, you may want to download it from my store here. (The basic version contains the same problems as this one, except questions are in multiple choice format. It also provides possible statements and reasons for students to choose from when completing or writing a proof. In addition, the basic version is designed with Zoom teaching in mind.)
This lesson (Geometric Proofs - Average to Advanced) is distance learning friendly. Share the blank guided notes with your students ahead of time and have them print them out. Then play the slide show on your screen and share the screen with your students.
Prerequisite knowledge: Students should have an understanding of how to use a definition, a postulate or theorem to justify a conclusion.
This lesson includes:
- Algebra properties (addition, subtraction, multiplication, division, substitution, transitive property, and reflexive property). Each property is accompanied by side-by-side examples from Algebra (which might be familiar to students) and Geometry (which is new to students).
- a practice section with 10 examples where students are challenged to recognize the property used in a sequence of 2 or 3 steps. I feel that being able to recognize a property is the first step in being able to use it in a proof. Unfortunately, many textbooks don’t provide enough practice to identify properties. Thus, I came up with my own examples, which made a transition to writing proofs much easier for my students.
- an introduction to two-column proof writing
- examples/practice of fill-in-the-reason proofs (3 problems)
- examples/practice of fill-in-the-blank (either a statement or a reason) proofs (7 problems)
- examples/practice of write-your-own proofs (8 problems)
- proofs of the Vertical Angles Theorem and the Linear Pair Theorem (can be used as more examples or more practice)
In this download, you will find 2 PowerPoint files:
1. blank guided notes (can be used as a student handout and/or a slide show by the teacher)
2. filled in guided notes (can be used as either a slide show or an answer key reference).
Students can follow the lesson easily, taking notes and working out examples as the lesson is presented. Problems in this lesson may be used as examples, guided practice or independent practice. Each slide is numbered for easy reference during the lesson. (I only number slides, not problems to avoid confusion.) Individual slides may be used as part of an interactive notebook.
Suggested printing for student handout or teacher reference: 4 slides per page with landscape orientation (this is what I use) OR 3 slides per page with portrait orientation. To avoid confusion, it helps for everyone in the class to use the same printing format.
Total number of slides: 47 in each file (94 in total)
