Modeling Subtraction of Fractions with Different Denominators Using Fraction Bars

This video tutorial teaches how to subtract fractions with different denominators using fraction bars. It begins with a review of subtracting fractions with common denominators, emphasizing the importance of using a common denominator to subtract numerators. The tutorial then demonstrates how to handle fractions with different denominators by converting them to equivalent fractions with a common denominator. Two examples are provided: subtracting 1/2 from 2/6 and subtracting 8/9 from 2/3, both using fraction bars to visualize the process. The lesson concludes with a recap of the key concepts learned.
