A great set of activities to engage students into thinking at critical levels.

When students really want to challenge themselves, we encourage them to try these activities. Brain teasers are puzzle or short questions that require you to think in an unconventional manner. This will help you develop strong skills that require to pay attention to simple details that most people will often overlook. These are great for helping students to learn analytical skills. You will be required to really understand what is being asked of you and the answer that you devise must be defensible. Once you come up with a solution, test it. Are there instances where solution does not hold up to reason.

The best way to approach these is to start with the Occam's razor technique which tells us that simplicity is often overlooked. Usually the simplest (, but not obvious) answer is often the correct one. You should first make sure you understand what the question is looking for. If you see any holes in the question, look for sense of clarity. Many of these problems will have several acceptable answers. Ask yourself if this question is one of those circumstances. When reading the question look for words that may have multiple meanings, the answer or path toward the solution often resides within those words or concepts. Have fun with all the brain teasers that you will find below. We offer answers for them, but in many cases another answer may suit it as well.
