Mathematics problems, games, and articles


Each month the mathematics enrichment site NRICH offers a series of logic-challenging and brain-draining puzzles in four stages, ranging from simple and colorful to scarily complex. But it's all done in a fun and non-threatening way. Should one "do" all of that month's puzzles, the other month's offerings are easily selectable.
