This standard begins the formal foundation of the idea of area development. Since we measure area in square units, it is natural to begin with rectangles and partition them into square regions so that we can easily count the total. Unit 5.7.

Thinking fractions with different numerators and denominators are not equivalent. We have added and subtracted fractions. In this lesson we will multiply fractions. When we add and subtract fractions, we count how many of the same size parts there are. When we multiply fractions, the sizes of the parts change. Consider this multiplication problem: . Introduction. In this chapter you will learn to add fractions with different denominators (a recap). You will learn to work backwards and split an algebraic fraction into components called ‘Partial Fractions’. Which is an equivalent fraction? .  . A. . B. . C. . D. .  .

This project is designed for Mrs. Maccani’s 3. rd. grade class.. The purpose of this project is to understand the relationship between whole numbers, simple fractions, and decimals. Students will demonstrate their understanding of equivalency and problem solving related to fractions and decimals.. 6.2.1 Multiplying Fractions. 6.2.2 Dividing Fractions. 6.2.3 Dividing Mixed Numbers.
