Expression Evaluation with Different Denominators: Adding Mixed Fractions of Water

Curated and Reviewed by Lesson Planet

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
