Matching LCD to Pairs

Worksheet Description

This worksheet is a mathematical exercise focused on finding the least common denominator (LCD) of different sets of fractions. It is structured as a matching activity where students are presented with pairs of fractions and a list of numbers on the side. The task is to identify the smallest number that is a common denominator of each fraction pair and match the fractions to this number. The goal is to practice the skill of determining the LCD to facilitate operations involving multiple fractions.

The worksheet is teaching students the concept of the least common denominator, which is the smallest common multiple of two or more denominators. By matching fractions to their correct LCD, students learn to analyze and compare denominators to find the smallest number that both can divide into evenly. This skill is crucial when combining fractions through addition or subtraction, as it requires a common denominator. Understanding how to find the LCD also lays the groundwork for more advanced mathematical operations, such as adding, subtracting, and comparing fractions.
