These puzzles are simple enough for anyone to try, but need some thinking to see how they work. They are based on logical thought rather than knowledge or memory or skill or arithmetic. They are also counter-intuitive (another way of saying that they're tricky!) Even if you can't work them out for yourself, once you know the trick, you can fool other people.

"A research team led by Carnegie Mellon University's Robert Siegler has identified a major source of the gap -- U. S. students' inadequate knowledge of fractions and division. Although fractions and division are taught in elementary school, even many college students have poor knowledge of them. The research team found that fifth graders' understanding of fractions and division predicted high school students' knowledge of algebra and overall math achievement, even after statistically controlling for parents' education and income and for the children's own age, gender, I.Q., reading comprehension, working memory, and knowledge of whole number addition, subtraction and multiplication. Published in Psychological Science, the findings demonstrate an immediate need to improve teaching and learning of fractions and division."

"For the first time, scientists have identified the brain pathway that links a positive attitude toward maths to achievement in the subject. In a study of elementary school students, researchers at the Stanford University School of Medicine found that having a positive attitude about maths was connected to the better function of the hippocampus, an important memory centre in the brain, during the performance of arithmetic problems. The findings will be published online Jan. 24 in Psychological Science."

"As Markov chains have become commonplace tools, the story of their origin has largely faded from memory. The story is worth retelling. It features an unusual conjunction of mathematics and literature, as well as a bit of politics and even theology."

"a man who figured out how to have his pi and recite it, too - beyond 60,000 decimals. All it took was intensive practice and a knack for storytelling, a new study finds."
