Each tape 2223 minutes, Grades 4 and up
A threepart series that combines colorful animated graphics with imaginative examples to explain fractions and how they are used and manipulated. Part I describes what fractions are and why they are useful. Numerator and denominator are defined and illustrated. Work with fractions begins by finding the fraction of a number. Part II illustrates the concepts of equivalent fractions and how to simplify fractions. Improper fractions are discussed and their relationships to mixed numbers are explained. Part III covers the addition and subtraction of fractions and mixed numbers. Problems from daily life are presented with bright, colorful animations. Each lesson ends with a review, and sample problems are used where appropriate.
FRACTIONS AND ALL THEIR PARTS: PART I
LESSON ONE develops an arithmetic understanding of fractions using common experiences such as half a glass of milk and onequarter of an hour. Fractions are illustrated as parts of a whole or set.
LESSON TWO covers naming fractions. The parts of a fraction, the numerator, and denominator are defined. Numerous animated examples are used to assist in these explanations.
LESSON THREE demonstrates how to find the fraction of a number. Several examples are used, and each step is illustrated and explained. The numerical manipulations are animated for clarity.
FRACTIONS AND ALL THEIR PARTS: PART II
LESSON ONE defines equivalent fractions. Colorful animations provide clear examples to illustrate equivalent fractions of a whole and of a set.
LESSON TWO shows how an understanding of equivalent fractions is used to simplify fractions. The idea of finding the common denominator is explained and illustrated with numerous examples.
LESSON THREE describes improper fractions and how they relate to mixed numbers. Several animated examples show how improper fractions can be renamed as mixed numbers.
FRACTIONS AND ALL THEIR PARTS: PART III
LESSON ONE utilizes ordinary experiences, such as the amounts of snowfall, to introduce adding fractions. The examples illustrate how to add and subtract fractions of the same denominator.
LESSON TWO illustrates how to add and subtract fractions with different denominators. Equivalent fractions are used to explain how to find a common denominator.
LESSON THREE shows how to add and subtract mixed numbers. Mixed numbers are changed to improper fractions and common denominators are found.
