## Problem Sets:

MOEMS past tests.

I received several past problem sets from the Math Olympiad when I signed us up. I tend to use these as take home problems that we discuss the next week. There's also a problem of the month on the site. I've found these to be hit or miss in terms of interest.

Math Counts.

I've picked up a ton of past tests and books from a friend who runs the local version of this contest. These I've also been using selectively to find a challenge problem for the week.

Art of Problem Solving Pre-Algebra.

I occasionally steal one of the challenge problems that seemed to work well for my son when he tried them out. Purple Comet Math Meet.

http://purplecomet.org

A fairly challenging online math contest aimed at Middle School and High School. The old problem sets are a great resource even if you don't do the contest.

UW Math Hour Olympiad.

There are not a lot of problems here but they're all really good. Look about half way down on the page.

Park City Mathematics Institute:

I liked the tiling problem sets I found in the beginning. I haven't fully decided if they are at the right skill level.

6 Problem/Posters that are all really fun:

http://www.furthermaths.org.uk/favourite

Project Gutenberg's Amusements in Mathematics, by Henry Ernest Dudeney

This was published in 1916 but the puzzles are still fun.

http://nrich.maths.org/frontpage - British site with a lot of interesting pre-canned lesson ideas across multiple grade levels.

http://www.cemc.uwaterloo.ca/resources/potw.php Problem of the week from U Waterloo. I find these a bit dry / too close to homework but I may take advantage of them in the future.

http://www.mathteacherscircle.org/ Expii's problems of the week. Po-Shen Loh the author is the coach for the national team.

http://areamaze.com Its only one type of problem as the name suggests but they're fun.

## Sites:

* http://www.mathcircles.org/GettingStartedForNewOrganizers_WhatIsAMathCircle_CircleInABoxThis has a great document showing sample sessions and topics used by various math circles. This was one of my favorite initial reads.

* http://www.numberphile.com/

This is a fun site and occasionally it has a topic that translates really well into the afterschool setting.

* http://www.artofmathematics.org/books

Large collection of material aimed originally at inquiry based learning at the college level. But its

highly adaptable.

* fivetriangles.blogspot.com

My favorite collection of challenge problems. Its

__updated fairly frequently but currently closed. Your best bet is to follow five triangles on twitter and save all the problems he posts there.__

__My selected saved problems are here: http://mymathclub.blogspot.com/p/five-triangle-problems.html__

__* http://solvemymaths.com/__

Another set of interesting puzzles and problems.

* http://www.gogeometry.com

Another interesting but fairly difficult set of geometry problems. I haven't fully reviewed yet to

see if any are usable at this level.

* http://artofproblemsolving.com/mathcounts_trainer

Brand new site from AoPS with MathCounts style problems to solve online.

* https://www.math.hmc.edu/funfacts/

A large set of interesting mathematical curiousities. These look great for starting off a session.

* graph theory for kids http://jdh.hamkins.org/math-for-eight-year-olds/

* brilliant.org

* http://www.mathteacherscircle.org Math Circle Teacher's Network. Some very interesting videos and general advice on getting started.

* https://www.facebook.com/groups/1001mathcircles/ The natural math facebook page. This is very active.

* https://undergroundmathematics.org/ Ok this is really a high school site out of Cambridge aimed at GCSE exams. But the underground map is so charming I'm including it anyway.

### Blogs

* http://www.mathandmischief.com/ A homeschooler who appears to have similar mathematical taste to me. I like her recent video lists.

### Worsheets:

http://www.kutasoftware.com/ A set of standard worksheets on various topics. Possibly useful as warm-up material in small doses.

## Books:

http://www.amazon.com/Mathematical-Circle-Diaries-Year-Curriculum/dp/0821887459I liked this one because it had a week by week description of what this circle did. Especially initally it was interesting for leveling and ideas about how long various activities took. Its also continues to be helpful as a source of ideas for topics.

http://www.amazon.com/Moscow-Math-Circle-Week-Week/dp/0821868748/ref=pd_sim_b_1?ie=UTF8&refRID=07PDCP0Q1G8D3K4PASBH

This one is more straight problem sets. I haven't used it much yet but I'm thinking about doing a solve-a-thon at some point and reusing their sets.
