JUST-IN-TIME MATHS

Taking intermediate algebra but find that you have forgotten some basic skills dealing with fractions in pre-algebra? Studying trigonometry and needing a review of FOIL from elementary algebra so that you can successfully simplify a trigonometric expression? These lessons may just be the help you need!

Just-in-Time Maths lessons are intended as a quick review of a specific topic that you have learned before but with which you are feeling a bit rusty. They are NOT intended as complete lessons for topics you have not previously studied. Each lesson provides links to tutorial videos, written lessons with practice problems, and online games or resources. We hope you find the information timely in helping you be successful in your current mathematics course.

DIRECTIONS: Choose a topic your need to study. Click HTML for the web version or PDF for the printable version.

Formula Reference Sheets

Students reviewing topics from a previous course sometimes find having a sheet of formulae useful. While it is not sufficient to just have the formula at hand -- you do also need to understand how and when to apply it -- these sheets do provide useful summaries.
