Description
This PowerPoint is designed with Zoom teaching in mind. However, it can be adopted for other distance learning platforms, as well as for teaching in the physical classroom (with some tweaks). This PowerPoint is designed to serve as a basic introduction to proofs. It contains guided notes, examples and practice problems.
This lesson is suited for classrooms and students with average math skills as well as for struggling students, as most questions are multiple choice, and most proofs have statement and reason lists to choose from. If you wish to adopt this lesson for stronger students, you may want to delete the slides that have statement and reason lists. (Alternatively, may want to download my PowerPoint Geometric Proofs – Average to Advanced from my TpT store here, which includes exactly the same problems as this file, but without answer choices provided.)
This lesson is also designed to increase student class participation during distance learning as each student’s active response is required for most problems.
What makes this PowerPoint unique, is that it utilizes Zoom capabilities for student response built into the problems. For multiple choice questions, students are asked to click yes, no, go slower or go faster as one of their response choices. The teacher will have instant access to student responses (summary stats and individual responses). For fill-in-the-blanks proofs, possible statements are reasons are provided and are color coded. Students are asked to order the reasons (or statements), and then stack colored LEGOS to show the correct order.
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 of identifying 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 Linear Pair Theorem (can be used as more examples or more practice)
Included are 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, filling in the blanks and working out examples as the lesson is presented. Some of the examples may be used as guided or independent practice. Each slide is numbered for easy reference during the lesson. (I don’t number problems, only slides 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.
Total number of slides: 59 slides in each file (118 in total), plus teacher instructions
