Description

Class Experience

This is an interactive class in which students are encouraged to contribute to the conversation.  As we work through puzzles that involve US coins, students are asked to describe what they see, what is the next step, and why that is the best move. Descriptive analysis is something that the best mathematicians and engineers do as a matter of course. 

Our coin puzzles involve addition, subtraction, multiplication, pattern recognition and logic. Much of our focus in this course will be on the logic of problem solving and the concept of the well-posed puzzle (problem). We will discuss unique solutions, data sufficiency (do we have enough clues to arrive at an answer), and data redundancy (is there a clue that is not necessary). These are concepts that are important for algebra word problems and geometry proofs.
Puzzles and games challenge us to think outside the box but unfortunately they are not typically included in the standard K-12 math curriculum. I love puzzles and I have used them in my teaching for years because I know that they promote critical thinking. Being able to explain your solution procedure in clear and concise language is an important skill that applies across all subject areas.

As an engineer I have worked with many very talented people who were great problem solvers but poor communicators. For me the ability to communicate and to explain your engineering or puzzle solution is as important as the problem itself.
Students will be given challenge puzzles to solve at the end of each class.  
 1 file available upon enrollment
Students will receive an introductory handout that can be completed before the start of the course. Challenge puzzle handouts will be distributed at the end of each class.
55 minutes per week in class, and an estimated 0 - 1 hours per week outside of class.
