This video demonstrates how to use the set model to add fractions with unlike denominators. Students need to have the prerequisite conceptual knowledge of finding like denominators before they can apply addition strategies to fractions with unlike denominators. The set model is beneficial for students who do not have automaticity with mentally determining multiples because they can count and move pieces to determine a like denominator.

This video demonstrates how to use fraction tiles to add fractions with unlike denominators. Teachers should model how to find like denominators to solve addition problems and students who struggle may benefit from using a multiples chart. Students should also have many opportunities adding fractions that have a sum equal to or greater than 1.

This video demonstrates how to use the fraction tiles for add fractions with unlike denominators. Students may write the multiples for each denominator to determine the least common denominator. Fractions tiles can be used to show how to represent equivalent fractions with the least common denominator.
This video demonstrates how to use fraction circles to add fractions. If students are adding fractions with unlike denominators, they can also practice finding the missing part of the whole as a solution strategy.
This video demonstrates how to use fraction tiles to add fractions. Fraction tiles easily allow students to practice adding fractions of like or unlike denominators. Students should be familiar with the concept of mixed numbers or improper fractions before using fraction tiles to add fractions that will equal a fraction greater than 1.
This video demonstrates how to teach students to think flexibly about fractions. Similar to whole numbers, fractions can be put together and taken apart in many different combinations. Students should practice identifying these combinations so that they can become fluent with fraction addition and subtraction.
This video demonstrates how to use fraction tiles to model fraction addition with unit fractions that sum to 1. After a teacher models how to appropriately use fraction tiles to solve addition problems, students can use the tools to explore fractions with guided and independent practice.

This video demonstrates how to use benchmark fractions, such as ½, to compare fractions with unlike denominators. When students show that they are proficient comparing fractions using concrete manipulatives or pictorial representations, they may be ready to compare fractions using reasoning strategies without representations. For beginners and for students who struggle, it may also be important for teachers to model to students how to check their work using other tools, such as fraction tiles.
