  1. Algebra Problem of the Week - Math Forum
    Algebra problems from a variety of sources, including textbooks, math contests, NCTM books, and puzzle books, and real-life situations, designed to reflect different levels of difficulty. The goal is to challenge students with non-routine problems and encourage them to put their solutions into words. Different types of problems are used to reach a diverse group of algebra students. A Teacher Support page is available for some problems. more>>

  2. Geometry Problem of the Week - Annie Fetter, the Math Forum
    The Geometry Problem of the Week (PoW) is a regular feature of the Math Forum, providing students an opportunity to answer questions and receive feedback and recognition from Forum staff. A Teacher Support page is available for some problems. more>>

  3. Math Fundamentals Problem of the Week - Math Forum
    Math problems for students working with concepts of number, operation, and measurement, as well as introductory geometry, data, and probability. The goal is to challenge students with non-routine problems and encourage them to put their solutions into words. A Teacher Support page is available for each problem. more>>

  4. Monthly Themes - NRICH Maths, Univ. of Cambridge
    Past problems from the NRICH Online Maths Club, archived by month. Each problem has a symbol indicating the stage, which tells you how little or how much mathematics you need to know to solve the problem but is no indication of its difficulty. The five stages correspond to ages 5-7, 7-11, 11-14, 14-16 and 16-18, and indicate that students in the UK normally meet the maths required during that key stage. more>>

  5. Pre-Algebra Problem of the Week - Math Forum
    Math problems for students learning algebraic reasoning, identifying and applying patterns, ratio and proportion, and geometric ideas such as similarity. The goal is to challenge students with non-routine problems and encourage them to put their solutions into words. A Teacher Support page is available for each problem. more>>

  6. Sites with Problems Administered by Others - Math Forum
    Problems of the week or month: a page of annotated links to weekly/monthly problem challenges and archives hosted at the Math Forum but administered by others, and to problems and archives elsewhere on the Web, color-coded for the level(s) of the problems posted. more>>
