In this presentation, students are given a refresher on the steps involved in adding and solving fractions. However, this knowledge is extended by looking at lowest common denominators, as well as reducing or simplifying fractions.
This presentation is part of a larger unit designed to develop proficiency in solving problems related to addition and subtraction of fractions by applying their understanding of equivalent fractions. The focus is on mastering the skill of manipulating fractions to facilitate efficient computation and problem-solving.
