Sudoku. Solve some sudoku puzzles. While doing so, think avbout what methods you are using. Could you explain them to someone else? Can you invent a trick that you didn't previously know to help you solve them faster? Can you learn such tricks from others?
There is also some reading on the "schedule" page (link at the left of the screen) and a few resources from which you can access sudoku puzzles to try.
