An interactive challenges mathematicians to add mixed fractions with unlike denominators. Five questions—fill-in-the-blank and multiple-choice—build from one to the next leading the way to an open discussion about denominators and factors. A helpful tool showcases a graduated cylinder and three beakers filled with water that scholars poor from one container to the next.

Instructional Ideas
- Bring the interactive to life—have beakers, a graduated cylinder, and water available for learners to pour and examine
- Assign the link for homework, prepare class members to discuss question five when they return to school the next day
- Review each problem with the class, encourage participation, and clear up any confusion
Classroom Considerations
- Create a free CK-12 account to access the interactive
- Questions build from one to the next
- Participants should know how to simplify fractions
Pros
- The tool's red dot is easy to move
- A link offers hints to help solve problems
- Feedback is given immediately after responses are chosen
Cons
- Fractions on the graduated cylinder are spaced closely together, which makes seeing correct amounts difficult
