Explore 20 minutes After reviewing some types of proofs that students have already used, I say that we are going to learn a new form of proof called mathematical induction.
I give students the three steps of the process: I talk more about this in the video below. Once students understand the general procedure, I will walk them through this example. I will randomly call on students to answer questions throughout the process to make sure that they understand as we go.
In this video I go through my strategy for getting from step 2 of induction to step 3 by writing what their goal is. After this proof has been completed, I go back to the domino analogy and revisit the concept one more time.
Then we know it will work for the next value, and the next value, and so on. Notes - Mathematical Induction.
I will usually set up the goal together with the entire class so they know what they are shooting for. After they have time to complete it, I will choose a student to share their work on the document camera.
I stress that they are writing a valid argument that needs to be clear and easy to follow.
They must be explicit in their steps and explain their thinking — just like if they were making an assertion in an English paper. If in an English paper they made the claim that Brutus was not an honorable man — they would give evidence to support their claim.
Proving in math is no different; if you claim that two expressions are equal, you should have evidence to support that.

Finally, I will assign 3 — 4 questions from their textbook to give them some practice with mathematical induction.What are some good books to read in order to improving mathematical proof and reasoning skills? Answered Apr 26, · Author has answers and k answer views.
What books can I read to learn about writing and reading mathematical proofs? Mathematical Reasoning: Writing and Proof is designed to be a text for the ﬁrst course in the college mathematics curriculum that introduces students to the processes of constructing and writing proofs and focuses on the formal development of mathematics.
The primary goals of the text are to help students: • Develop logical thinking skills and to develop the ability to think more. Reasoning and Proof and proofs; select and use various types of reasoning and methods of proof.
Mathematical reasoning and proof offer powerful ways of developing and expressing insights about a wide range of phenomena. People who reason and think analytically only experience in writing proofs has been in a high school geometry course.
INTRODUCTION TO MATHEMATICAL REASONING Worksheet1 Examples of proofs 1 Key Ideas follows from the hypothesis (what is assumed to be true).
There are many di↵erent ways to write a proof, and trying to constrain proof writing to an algorithm will sooner or later be lim- about such proof (this is a subjective question, so there isn’t a.
This is a fun little geometry activity that should help students understand the importance of using deductive reasoning skills - and see why proofs aren't useless after all. Mathematical Reasoning: Writing and Proof is designed to be a text for the ﬁrst course in the college mathematics curriculum that introduces students to the pro- cesses of constructing and writing proofs and focuses on the formal development.
