At White Crane Education we believe that to be a part of a community, you can't just profit from it. You have to contribute to it.
Our classrooms section has a variety of free classrooms for use by students and their teachers. These online tutorials take students through material not normally convered in a middle school or high school curriculum through a series of lectures that include real world applications and interactive applets. To use these applets you need to have at least version 1.5 of Sun's Java run time. If you're not sure if you have it or not, go to this page on Sun's website and click on the "Verify Installation" button. This will get the version your browser is currently using and give you a link to download the latest version if you don't already have it.
| General Mathematics | This short course covers general topics from introductory mathematics and arithmetic such as fractions and percentages. |  |
| Linear Equations | Linear equations are an important part of every algebra class. Not only do they illustrate many basic algebra principles but they're a basic tool in mathematical modeling. They can be used to describe everything from the motion of cars to the cost of manufacturing processes. | |
| Polynomials | Polynomials are one of the building blocks of engineering. They can be used to model everything from the behavior of falling objects to complex dynamic systems. Our short course covers classification, addition and subtraction, multiplication, factoring and solving equations including the Quadratic Equation. |  |
| Rational Expressions | Rational expressions are just fractions where the numerator and denominator are polynomials, i.e. they have variables rather than just numbers. That may sound simple enough but, when you start trying to work with them, they can turn out to be quite tricky. Not because the concepts are difficult but because there are a lot of calculations involving multiple polynomials that can quickly become very messy. This short course takes you, step by step, through all of the basic procedures you need to know to work with these objects. |
| Combinatorics | Combinatorics, part of our algebra 2 program, is the mathematical study of counting. Like number theory, this sounds deceptively simple. We all know how to count, right? Combinatorics includes formal methods for answering questions like, "How many ways can four boys and four girls be seated in a row if two boys and two girls can't sit next to each other?" where making a list would take days. |  |
| Number Theory | Number Theory, part of our Algebra 1 curriculum, studies the positive integers, i.e. the numbers 1, 2, 3, 4, ... What sounds like a really simple basis for a full branch of mathematics is actually a complex and diverse subject that is at the heart of modern cryptography. |  |
| Set Theory | Set theory is one of the funny subjects - at the same time abstract and practical. Our short course covers the primary topics with some great dynamic content to help illustrate them. As usual in a short course, we're focused on specific techniques and how to perform them. Our upcoming long course on the subject will cover the applied perspective in more detail. |
