Keys to Fractions, Decimals,
Percents, Algebra, Geometry and Measurement series of
workbooks are proven to successfully motivate students to
succeed. These self-paced, self-guided workbooks makes
each subject easier to learn. Minimal reading is
required, so students can easily work independently or in
small groups.

### Strengthen
Your Students' Mental Computation Skills

Key
to Percents
first emphasizes mental computation and estimation
skills—because most work with percents is done without pencil
and paper. Then students are taught to solve percent problems
using equal fractions and decimal multiplication. Finally,
percents are used to solve word problems in a variety of
applications. Key
to Percents
assumes only a knowledge of fraction and decimal computation. __Sample__

Book
1 Percent Concepts

Book
2 Percents & Fractions

Book
3 Percents & Decimals

### Review
Fractions with Your Students

Do
you have students who have never mastered fraction concepts or
who need a good review?

Key
to Fractions
covers all topics from basic concepts to mixed numbers and is
written with secondary

students
in mind. Minimal reading is required, so students can easily
work independently or in small

groups.
These self-paced, self-guided workbooks motivate students to
succeed. __Sample__

Book
1 Fraction Concepts

Book
2 Multiplying & Dividing

Book
3 Adding & Subtracting

Book
4 Mixed Numbers

### Build
Students' Decimal Skills with Real-World Applications

Key
to Decimals
begins with basic concepts and operations on decimals. Then it
covers real-world

uses
of decimals in pricing, sports, metrics, calculators, and
science. The success-oriented approach

of
Key
to Decimals
builds confidence and independence. You'll find this series to
be a great way to

prepare
for standardized tests. __Sample__

Book
1 Decimal Concepts

Book
2 Adding, Subtracting & Multiplying

Book
3 Dividing

Book
4 Using Decimals

**Cover
Measurement with Easy-to-Use Workbooks**

Students
using Key
to Measurement
enjoy a variety of hands-on experiences related to the English
system of measurement. Group projects are included in addition
to numerous individual activities. Book
1 teaches students how a linear measurement system is developed
and then presents interesting and fun activities related to
measuring length. Book
2 focuses on length, perimeter, and area measures. Book
3 develops the concept of area and introduces students to
volume. Book
4 covers a variety of topics with students weighing objects,
measuring capacity,
and learning about temperature and time. __Sample__

Book
1 English Units of Length

Book
2 Measuring Length & Perimeter Using English Units

Book
3 Finding Area & Volume Using English Units

Book
4 Metric Units for Mass, Capacity, Temperature, & Time

### Introduce
Your Students to Algebra in Simple Terms

Key
to Algebra
offers a unique, proven way to introduce algebra to your
students. New concepts are explained in simple language, and
examples are easy to follow. Word problems relate algebra to
familiar situations, helping students understand abstract
concepts. Students develop understanding by
solving equations and inequalities intuitively before formal
solutions are introduced. __Sample__

Book
1 Operations on Integers

Book
2 Variables, Terms, & Expressions

Book
3 Equations

Book
4 Polynomials

Book
5 Rational Numbers

Book
6 Multiplying & Dividing Rational Expressions

Book
7 Graphs

Book
8 Graphs

Book
9 Systems of Equations

Book
10 Square Roots & Quadratic Equations

**Ease
Your Students Into Geometry**

Key
to Geometry
offers a non-intimidating way to prepare students for formal
geometry as they do step-by-step constructions. Students
begin by drawing lines, bisecting angles, and reproducing
segments using only a pencil, compass, and straightedge. Later
they do sophisticated constructions involving more than a dozen
steps and are prompted to form their own generalizations. When
they finish, students have been introduced to 134 geometric
terms and
are ready to tackle formal proofs. __Sample__

Book
1 Lines & Segments

Book
2 Circles

Book
3 Constructions

Book
4 Perpendiculars

Book
5 Squares & Rectangles

Book 6 Angles

Book
7 Perpendiculars & Parallels, Chords & Tangents, Circles

Book
8 Triangles, Parallel Lines, Similar Polygons
