Basic Essentials of Mathematics: Book Two, Percent, Measurement & Formulas, Equations, Ratio & Proportion

This book has excellent worksheets to teach measurement and conversion of units. This book has saved me hours of time making up my own materials. It could have some more pictures and visual aids but it is a great source anyway.

The Basic Essentials of Mathematics is a two book series that deal in the basics of math. I use these books for my Adult Basic Education and GED classes. Once a student has completed the two books they have enough math to successfully pass the GED exam. I like these books because it covers all the basic functions in only two small books in which students feel comfortable and and not as overwhelmed as they often do with the big GED books on the market. These books are self directed and can be used by anyone whishing to improve on all that high school math they have forgotten.
