Use it.
Get your math on track!
Designed for students who have already studied math up to algebra, Math Essentials finds and fills the gaps that hinder algebra studies. The program assumes a student has mastered basic addition, subtraction and multiplication, but it addresses division, if needed, as this was commonly found to be weak. It isn’t designated for use with a specific age or grade, but is addressed to students preparing to study algebra, and has most often been used with teens. It is best suited for Grade 7 through Grade 10 (ages 12-15).
The program includes a variety of tools an instructor can use to tailor the program to a student’s needs. The Comprehensive Diagnostic Test identifies which math skills the student hasn’t already mastered. The individual learning guide for each unit allows the student to study just what is needed. A variety of exercises allow the student to practice as much as needed and to stay sharp on skills learned.
Each of the skills covered in the program are provided in individual books as well as all together in one full book. Learning guides and exams are provided for each skill, and may be used with both the appropriate individual books and the full book.
