Evaluating Expressions Involving Fractions

The video tutorial guides sixth graders through evaluating expressions with fractions, emphasizing the importance of using the order of operations (PEMDAS). It begins with a review of evaluating expressions with whole numbers and introduces the concept of variables and substitution. The tutorial then focuses on solving expressions with exponents, simplifying fractions, and applying the order of operations to division and addition. It also covers finding common denominators for adding fractions and concludes with a reminder to take time and follow fraction rules.
