The key to multiplying and dividing decimals is attention to the number of decimal places, including when to add zeros. This book provides practice with place values, estimation, and multiplication and division of decimals in word problems using everyday situations.
There are 20 books in the Pre-Algebra series. The first books continue from the Fraction series with more work on fractions and decimals. Books progress through percentages, proportions, metrics, scientific notation, order of operations and finally, probability in Book 20. Students who complete the Pre-Algebra series are now fully ready for Algebra (coming soon).
