Converting Fractions and Decimals

Mrs. Zia's lesson focuses on converting between fractions and decimals using equivalent fractions. Students learn to represent rational numbers in different forms based on real-life contexts, such as recipes and currency. The lesson covers using place value to convert decimals to fractions and vice versa, emphasizing denominators that are factors of 10, 100, or 1,000. Through examples, students practice simplifying fractions and understanding decimal place values. The lesson concludes with a summary of key concepts, reinforcing the ability to convert any terminating decimal to a fraction using place value.
