Many people enjoy working on grid puzzles as small, quick challenges of their mathematical and logical skills. Here is one you may not have seen, the OkiDoku. How does it work? Looking at the grid above, try to find four different numbers and put them in these 16 squares in a way that will satisfy the following two conditions:

Technology is here to stay. There are two main ways of interfacing with technology: passively as a user and actively as a developer. Today's technical problems are very complicated -- they cannot all be solved in theory on a whiteboard or exhaustively via computation. The use of simulation methods to obtain a "solution" to the problem at hand is not uncommon in industry. The purpose of this post is to provide broadly a "why" and "how to" for introducing simulation methodologies into high school math and programming courses. While the subject matter is technically deep, the concepts are well within the grasp of high school students -- and possibly younger students.

Summer is the time when new teachers learn and when veteran teachers relax and then learn. Whether at the beach watching over your kid who is flinging the beach ball too hard, or at home with your face right on the full-power air conditioner, here's hoping the following five books give you something to enjoy and discuss. These books fall into three categories: leadership, race, or math (and in one case, all three). I'm recommending them all, and feel free to let me know what you think in the comments section below.

For the past two months, I've been the only teacher in the world to have Google Glass -- the most highly anticipated (and intensely coveted) technology to emerge in years. How did I get this incredible opportunity? Let me explain . . .

If ever you come across a set of math teachers, whether at a common planning meeting or a bar during happy hour, bring up the conversation of calculators and watch the sparks fly. The arguments for and against calculators have the spirited vigor of a Red Sox vs. Yankees game without the animus. One side argues for the use of efficient and available technology in the classroom, while the other argues for numeracy and fluency to the highest order.

Sammamish High School has defined seven key elements of problem-based learning used in our classrooms. This week we will explore the key element of academic discourse. How students communicate their discoveries and connect them to the overall learning is an essential part of what we do. Without proper communication, progress cannot be made on many projects.

There is lots of talk about the science, technology, engineering and math (STEM) pipeline and all of its leaks. My personal mission is to fill the STEM pipeline with so many children that it bursts. To do this, STEM must be taught in an inspiring way. To keep children engaged, we need to bring passion for learning back into the classroom.

Considering project-based learning as a way to teach 21st century competencies? Or perhaps you have already used PBL in your schools and want support for your discussions with administrators, parents or board members? In either case, it might be helpful to know about the strong research evidence that PBL, when supported by good professional development, can in turn support the teaching and learning of 21st century skills significantly better than more traditional alternatives.

Financial Literacy Month is April -- just around the corner -- and it's never too early to prepare. Personally, I believe this is a great opportunity to use games in an intentional way to teach students financial literacy skills. Games can be used as a "hook" or anchor activity, as well an instructional activity that is revisited throughout a unit of instruction. A game can help scaffold the learning of important content as well as providing context for application of content. If you really trust the design of the game, it can also be an excellent assessment tool!
