Why do we do proofs?

The aim of this session is to motivate students to understand why we might want to do proofs, why proofs are important, and how they can help us. In particular, the student will learn the following: proofs can help you to really see WHY a result is true; problems that are easy to state can be hard to solve (Fermat's Last Theorem); sometimes statements which appear to be intuitively obvious may turn out to be false (the Hospitals paradox); the answer to a question will often depend crucially on t

The Language of Mathematics (28): Proofs Involving a Line, Part 2

Clear, straightforward instruction involving how to solve proofs. Instructor uses a small chalkboard for demonstration.

Sizing Up Servings : Assessing Definitions of Recommended Food Portions

With the growing concern over unhealthy eating habits in the US, this lesson plan from the New York Times Learning Network offers a timely and interesting look at the concept of serving size. The lesson helps students understand the definition of a suggested serving size and re-define their daily food intake in terms of these recommended amounts. A recent New York Times article on the topic plus an extensive set of classroom activities form the basis of the lesson, which requires about one hour

Examples of Deglaciation

This site features visual resources that illustrate the deglaciation of North America after the last glacial maximum. Animations and supporting text demonstrate glacial retreat and the flooding of the Bering Land Bridge between Alaska and Russia. These resources may be incorporated into lectures, labs, and other activities.

Simplifying Rational Exponent Examples

This video builds on instructor provided in a separate video about the rational exponent rule. The instructor begins with a brief review of this rule, then begins to explain some example problems that apply the rational exponent rule as well as knowledge of how to work with radicals.

Examples of Campus-based Learning

This site provides several examples of campus-based learning. Topics include environmental assessment, the nitrogen budget, campus greenhouse gas emissions, eco-houses, and biodiversity.

Examples of Solving Multi-Step Inequalities

A teacher walks students through the explanation of how to solve four different mult-step one variable inequalities. This includes using the distributive property, combining like terms first, and check if a value is a solution.

Logic & Proofs

This is an introductory course designed for students from a broad range of disciplines, from mathematics and computer science to drama and creative writing. The highly interactive presentation makes it possible for any student to master the material. Concise multimedia lectures introduce each chapter; they discuss, in detail, the central notions and techniques presented in the text, but also articulate and motivate the learning objectives for each chapter.
Topics Covered: The notions of statem

Connotation and Denotation With Examples

This short video is a student-made production explaining the difference between connotation and denotation. In the video, students define connotation and denotation and provide two examples of words that have different connotations and denotations.

Examples of How to Solve Mutiplication by Multi-Digit Numbers

Multiplying multiplying-digit numbers. Four examples are shown on a white board and the problems are solved with a marker on the board. This video is silent.

How and why we do mathematical proofs

This is a module framework. It can be viewed online or downloaded as a zip file.
As taught in Autumn Semester 2009/10
The aim of this short unit is to motivate students to understand why we might want to do proofs (why proofs are important and how they can help us) and to help students with some of the relatively routine aspects of doing proofs.
In particular, the student will learn the following:
* proofs can help you to really see why a result is true;
* problems that are easy to state

Examples of Gallery Walk Questions

This site from SERC's Starting Point presents examples of Gallery Walk questions on various topics. The examples include learning goals, teaching notes and tips, material lists, resources and references.
