Nick's Mathematical Puzzles

Nick's Mathematical Puzzles
Welcome to my selection of mathematical puzzles. What's new? See puzzle 160. The math puzzles presented here are selected for the deceptive simplicity of their statement, or the elegance of their solution. Explaining how an answer is arrived at is more important than the answer itself. Each puzzle is assigned a level of difficulty of between one and four stars, with four being the most difficult. The source for each problem is given at the bottom of the solution page. I welcome feedback of any kind. Some brief biographical information. Nick Back to top Related:  History of Mathematics

Transum: Maths Puzzles There is a great amount of satisfaction that can be obtained from solving a mathematical puzzle. There is a range of puzzles on this page, all with a mathematical connection, that are just waiting to be solved. You can earn Transum Trophies for the puzzles you solve. Do you have any comments? Search Looking Back and Moving Forward Pre-K-2, 3-5, 9-12 This final lesson of the unit reviews the work of the previous lessons through a variety of activity stations, one of which involves using an interactive graphing tool. Students model with buttons and record addition and subtraction. Counting Embedded Figures Students look for patterns within given data and form generalizations for the problem, thereby sharpening the algebraic skills of the students. Building Connections This lesson focuses on having students make connections among different classes of polynomial functions by exploring the graphs of the functions. Counting Embedded Figures This grades 7-12 activity allows students to look for patterns within the given data. Explorations with Chance In this lesson, students analyze the fairness of certain games by examining the probabilities of the outcomes. Exploring Linear Data Students model linear data in a variety of settings that range from car repair costs to sports to medicine.

Patterns are math we love to look at Why do humans love to look at patterns? I can only guess, but I’ve written a whole book about new mathematical ways to make them. In Creating Symmetry, The Artful Mathematics of Wallpaper Patterns, I include a comprehensive set of recipes for turning photographs into patterns. The official definition of “pattern” is cumbersome; but you can think of a pattern as an image that repeats in some way, perhaps when we rotate, perhaps when we jump one unit along. Here’s a pattern I made, using the logo of The Conversation, along with some strawberries and a lemon: Mathematicians call this a frieze pattern because it repeats over and over again left and right. When we can do something to a pattern that leaves it unchanged, we call that a symmetry of the pattern. You can make frieze patterns from rows of letters, as long as you can imagine that the row continues indefinitely left and right. What other symmetries does it have? Suppose a pattern stays the same when you flip it about a mirror axis.
