Subtracting Fractions with Like Denominators Using an Area Model

This lesson teaches how to subtract fractions with like denominators using an area model. It explains the components of fractions, common mistakes in subtraction, and provides examples of subtracting fractions such as 5/6 - 2/6 and 5/8 - 2/8. The lesson emphasizes the importance of using area models to accurately represent fractions and highlights the need to subtract only the numerators when denominators are the same.
