Nick’s Mathematical Puzzles
Age Range: 11 and up (Grades 5-12, with parental supervision)
At this website you’ll find a collection of more than 100 math puzzles that cover algebra, geometry, probability, number theory, trigonometry, calculus, and logic. They have been selected “for the deceptive simplicity of their statement, or the elegance of their solution.” While they will challenge your cleverness, the site founder Nick Hobson (who has a math degree and works in computer software) says, they “usually only require pre-college math.”
When you get to the site you will see an introduction. Above it is a menu bar that currently provides access to 160 puzzles. View the “Index” to see the names of the puzzles archived here. Click on any one, and a new page opens with the puzzle. You’ll see 1-4 stars next to each puzzle title that designates the level of difficulty, with four being the most difficult.
As mentioned at the website, “Explaining how an answer is arrived at is more important than the answer itself. To this end, hints, answers, and fully worked solutions are provided, together with links to related mathematical topics. Further references are provided with many of the solutions. The puzzles are intended to be fun, with an educational element.”
