In this online interactive, students use a visual model to solve addition problems.

One goal of this task is to help students develop comfort and ease with adding fractions with unlike denominators. Another goal is to help them develop fraction number sense by having students decompose fractions. Because the Egyptians represented fractions differently than we do, it can also help students understand that there can be many ways of representing the same number.

This task asks students to find and use two different common denominators to add the given fractions. The purpose of this question is to help students realize that they can use any common denominator to find a solution, not just the least common denominator.

In this lesson, students will use nautical flags to apply their understanding of addition and subtraction of fractions with unlike denominators within context. This is remixable if you provide additional supports for the range of learners.

This task allows students to explore a situation involving the estimation, addition, and subtraction of fractions with unlike denominators. This is remixable by adding student work or you can upload a new resource also aligned to this standard.

The purpose of this task is to present students with a situation where it is natural to add fraction with unlike denominators; it can be used for either assessment or instructional purposes.

The purpose of this instructional task is to motivate a discussion about adding fractions and the meaning of the common denominator. The different parts of the task have students moving back and forth between the abstract representation of the fractions and the meaning of the fractions in the context.

The purpose of this task is to help students realize there are different ways to add mixed numbers and is most appropriate for use in an instructional setting.
