11 Math Problems That Look Simple But Are Not. If Brain Teaser Tuesday was a thing, THIS would be great for Brain Teaser Tuesday.

However, seeing as that is not a official thing (thanks for dragging your feet on that, OBAMA) -- these are just 11 math brain teasers for any old Tuesday. If you saw this list title and didn't recoil in horror, prepare to have all sorts of nerd fun. If you saw this list title and did recoil in horror, there are approximately 600 other lists on this website that you'll probably want to check out. Click here to go to a random one. And also, welcome to Costco, I love you. Because I respect you, I did not include the answers to these questions anywhere. (You can leave out the answer to the tennis problem, since there's really no way to add that in.

Get to it. Racks on racks on racks of squares in squares in squares.How many squares are in this image? ALL STRANDS - Open-Ended Math Problems. Open-Ended Math Problems This site is for the specific purpose of preparing Middle School students for OPEN-ENDED problem solving on standardized tests.

We have divided each month into the five strands from the Philadelphia math standards:Number Theory Measurement Geometry Patterns, Algebra, and Functions Data, Statistics, and Probability There are three levels of difficulty for each standard. We have written and chosen problems from different sources that lend themselves to more than one way of solving. It is our hope that if these are done on a consistent, weekly basis, the students will feel more confident and comfortable at test time. To better prepare for the tests, students should answer with a picture, diagram, or paragraph explaining the solution and how they determined their answers.

Joy of Mathematical Problem Solving This website is a resource for anyone who wants to enjoy creative math problem solving. Math games, puzzles, magic tricks and interesting real life contexts can be used to cultivate love for creative math problem solving. For ages, people have enjoyed activities such as games, puzzles and magic shows. Therefore, it is not surprising to find students enjoying similar activities based on mathematics.Underlying reasons why we enjoy games, puzzles and magic are somewhat different.

How do we nurture our instinctive love of puzzles, games and magic tricks so that we enjoy creative math problem solving? Dan Meyer's Three-Act Math Tasks. Math Problem Solver. NRICH. PhotoMath.net. Problem Solving - Potent Math Problems. . . . are problems that have the potential to deepen understanding of significant mathematics through multiple answers approaches to an answer interpretations extensions perspectives on a mathematical idea layers of complexity algorithms Problems with multiple solutions and/or multiple approaches are often called open-ended problems, although many other problems also go by that name.

Open and open-ended problems are frequently used in Japanese classrooms to achieve deep understanding of mathematical concepts. In American classrooms, they can be used effectively with teaching methods like the SPOSA model. Although we are developing a database of potent problems, we don't pretend that by themselves the problems will lead to deep understanding. The teacher counts. The database, which is appearing here slowly, is organized according to the content standards of NCTM Principles and Standards 2000: Ideas and suggestions are welcome.

What is a favorite potent problems? Probelm Solving - SPOSA. The SPOSA model of teaching Larry Copes This is problem-based teaching in the sense that the mathematical ideas grow out of work on the problem, rather than proceeding work on the problem.

Set the context. Math Tasks from LTC 4571 (Methods 1) Solving Algebra and Other Story Problems with Simple Diagrams. The Three Acts Of A Mathematical Story. 2016 Aug 6.

Here is video of this task structure implemented with elementary students. 2013 May 14. Here’s a brief series on how to teach with three-act math tasks. It includes video. 2013 Apr 12. Storytelling gives us a framework for certain mathematical tasks that is both prescriptive enough to be useful and flexible enough to be usable. Act One Introduce the central conflict of your story/task clearly, visually, viscerally, using as few words as possible. With Jaws your first act looks something like this: The visual is clear.

With math, your first act looks something like this: The visual is clear. Leave no one out of your first act. Act Two The protagonist/student overcomes obstacles, looks for resources, and develops new tools. Before he resolves his largest conflict, Luke Skywalker resolves a lot of smaller ones — find a pilot, find a ship, find the princess, get the Death Star plans back to the Rebellion, etc. So it is with your second act. What tools do they have already?
