Hello, and welcome to an Art of Problem Solving Math Jam. Today we'll be discussing Art of Problem Solving classes. We'll start with a few sample problems, so you can get a little taste of what the classes are like. Then, I'll give an overview of how our courses work, and answer any questions you may have about the courses.

The classroom is moderated: students can type into the classroom, but only the moderators can choose a comment to drop into the classroom. So, when you send a message, it will not appear immediately, and may not appear at all. This helps keep the class organized and on track. Also, only moderators can enter into private chats with other people in the classroom.

In this Math Jam, we will start off by doing a few sample problems. These will be drawn from our Introduction to Counting & Probability course. We won't be doing problems from all of the courses tonight, since that would take too long. Instead, we'll just do a batch of problems at the beginning of the Math Jam, and discuss the courses for the remainder of the class.

Please understand that if you are enrolled in one of our introductory classes, or haven't much experience yet with advanced problem solving, then much of the material we cover tonight might be well beyond you right now. We won't be able to teach you all the math you need to understand this material in one night! So, don't be frustrated if you don't understand the problems we discuss for those classes -- your time will come!

There is a much wider range of students here tonight than in our typical classes. So, some of you will find tonight's material very, very easy, and others will find it very, very hard. Also, because there's such a wide spread of students, we typically end up going a bit faster in the Math Jam than we do in class.

First, when it looks hard to count something directly, try counting the opposite of what you're asked for. We call this approach complementary counting, since 'complement' in dealing with groups of objects in mathematics roughly means 'opposite'. I also call this 'counting what you don't want'.

Second, when your restriction is that some of your items must remain together when putting them in a row, a useful tactic is to consider the items all together as a single item, as we did AliBrianna above. Then you separately consider how many ways you can order the items within the group.

These three basic examples show why it is pointless to memorize your way through counting - I can ask zillions of variations of the above questions. Instead of memorizing your way through each variation, you should learn when to add, when to subtract, when to multiply, and when to divide. Since you already know how to perform these operations, once you know when to do them, you know how to count!

** Ability to work independently. Students learn by struggling through difficulties. This means sitting in a corner and failing at something until it clicks. We provide structure for planning and approaching classes, and we love to help when students are stuck, but we also expect them to be responsible for keeping up with their work and reaching out to us when they need support.

** Desire to take on challenges. Our goal is to teach students how to solve problems they've never seen before. They only learn that skill by routinely encountering novel problems. This is a lot more difficult than simply regurgitating a mastered algorithm over and over. It's also a lot more fun and a lot more rewarding. Students who agree with that sentiment find a home at AoPS quickly.

It also helps to have a teacher on your side who knows your child when talking with school administrators. Many parents who have succeeded in securing credit for their children's work tell us that they've needed a "don't take no for an answer" attitude to overcome some schools' initial resistance to making special arrangements for their children.

b) You might get the counting skills you need from Volume 1. Intro to Counting goes into more detail than Volume 1, so if your skills aren't quite up to par, I'd take that first. You can use the Intermediate Counting pre-test to see if you are ready.

Okay so I have the following questions and that's it. . I've asked this question of forums and I would sincerly appreciate admins answering. a). Many people have relpied depends on you, but I'd like an estimate. Assuming that I wanted to finish the Geometry and Probability sections in Volume 1 how long would it take me on average.(pls give me an actual number) My previous post was too long so I will break it into parts

Unfortunately, it's just not possible to give an accurate estimate. How long it'll take you to finish any math textbook (or a particular part of a math textbook) can vary so much depending on your mathematical background, and how easy/difficult you generally find the subject(s) covered in that text. My rule of thumb for how quickly to go through a math text: just go at whatever speed you need to in order to thoroughly learn the material it covers.

That depends a lot on the course you are taking and those you have previously taken. I would recommend looking at an AoPS course that covers similar content, and checking out the pre-assessment for that AoPS course to see if you know the material well enough to move on.

It may just be a matter of finding the right course. Many of our courses are *very* difficult, especially if you do not have the requisite background knowledge. I'd start by looking at the earlier courses in our curriculum. Students who are eager and enjoy a good challenge tend to fare well with our curriculum. And just as a reminder: a little bit of struggle is good!

There's no metric that converts the colors to specific letter grades. If you ask for a letter grade at the end of the course, your instructor will take your entire body of work into consideration and use his or her best judgment in assigning a grade. Generally speaking though, students who are able to consistently get green and blue on their report receive A's.

Our Mathcounts Basics and Mathcounts Advanced courses are fantastic resources. You can also work on old Mathcounts problems. The AMC 8 often has similar questions, so working on old AMC 8 exams can be helpful too. Find the area you are weakest in, and study hard in that subject.

If you want to avoid that, I'd recommend talking to your school's academic advisor/counselor before taking an AoPS course, to see if they'd give you credit for that (or at least allow you to skip the corresponding class at school!) I'd recommend bringing along the syllabus of the class you're interested in taking when you go to talk to your school about this:
