Two Formats: Books vs CDs?

Both the softcover books and the CDs are written for the teacher.  Using the book requires the teacher to read the scripted lessons, while watching the CD requires the teacher to read from the screen.  Both versions provide a complete elementary math curriculum.  Both versions come with accompanying workbooks.  Both come in three levels: 

Level One:  K-2

Level Two: 3-5

Level Three: 6-8




The CD format has a little less content than that of the softcover book.  There are fewer exercises in the CD workbooks (#63 exercises in Level One compared to #104 exercises in the workbook for the Level One book). The book format has a slightly more thorough treatment of the basic skills and more practice.

Both cover the same scope of skills including Numbers, Counting, Addition, Subtraction, Place Value, Word Problems and Introduction to Fractions.The CD version includes time, money, measurement and geometry. 

Level Two in both the book and CD formats cover the Multiplication Facts, Division with and without remainders, Factors and Multiples, Prime Factorization, Least Common Multiple and Highest Common Factor, Adding and Subtracting Fractions, Mixed Numbers and Improper Fractions.  In only the CD Level Two  workbook, decimals and converting units of measure are also introduced.  

Level Three in both the book and CD versions cover Multiplying and Dividing Fractions and Decimals, Place Value and the Metric System, Converting Decimals to Fractions to Percents.

Both formats provide thorough math foundations in both concepts and skills and often accelerate the student by several years.
