Becoming Good at Math

Our class teaches practical math and cures the mindset "I am bad at math". It usually cures the mindset "I am afraid of math".

Study Skills

Besides the topics above, you will learn math study skills. Math classes have their own best ways to take notes, do homework, cooperate in groups, and prepare for tests.

If you have never been taught these study skills then of course you felt overwhelmed by previous math classes. You were actually trying to learn two classes at once: the math topics and these study skills. Then there was the extra problem that the second class is barely acknowledged.

We emphasize these study skills. Once you learn them, your classmates in future math classes will look at you and say, "You are such a good math student!" What they mean is, "I am still doing a double curriculum but you're not. You are passing the class while doing half the work."

This is one-third of becoming "good at math".

Math Tools

Math 20 is about foundational tools: ratios, percents, measurement conversion, percent change, sales tax, proportions, scale factors, unit analysis, basic geometry, and calculator use.

Math 20 only uses those foundational tools in the most basic way. But there is much more to learn about context.

As an analogy, a young child knows what a "pliers" is. They understand how to use one. But in real life there are many kinds of pliers, each appropriate in different situations, and each used slightly differently.

Math 25 assumes your understanding of those tools is vague and mostly forgotten. We review and build a solid understanding about how and when to use those tools in real life.

This is another one-third of becoming "good at math".

Big Issues

You will also be introduced to the delightful world of math issues without right answers.

Yes, we do small problems with right answers too. Those are the foundation of any discussion of big issues. We learn a few facts and formulas, and discuss their appropriate uses, practical help for decision making, and limitations. You will learn them and grow in math confidence.

But much more interesting than these small problems (that do have right answers) are the big issues.

Big issues involve depth and guidance. They are not small, shallow issues with certainty. They ask what does this kind of math mean for you? How can math help you make better health decisions, personal finance decisions, and business decisions? Those issues have no right answers.

Those big issues will introduce you to seeing life with a math worldview. The big issue answers you develop during class will continue to mature as you mature. This is how math helps quality of life.

This is the final one-third of becoming "good at math".

Allow the class to challenge you. Achieve your potential. Be pleasantly surprised by the height of your accomplishments.
