Ratio and Proportion

Curated and Reviewed by Lesson Planet
This Ratio and Proportion lesson plan also includes:
  • Ratio and Proportion
  • Join to access all included materials

Do these items have the same ratio? Through a learning contract, pupils master proportions by practicing proportions via word problems, graphs, and with manipulatives. An exit ticket checks for understanding at the end of the differentiated lesson.

Instructional Ideas

  • Use the learning contract as an assessment contract at the end of a unit on ratio and proportion
  • Create additional items similar to those in the non-negotiable section of the contract to provide additional individual practice

Classroom Considerations

  • The books that are needed are If Dogs Were Dinosaurs, If You Hopped Like a Frog, and If the World Were a Village: A Book About the World’s People
  • Geometer's Sketchpad is needed to complete the learning contract for the entire class

Pros

  • Teachers use a checklist in order to grade the learning contract and presentations
  • The learning contract allows for class members to take ownership of their learning

Cons

  • A specific Geometer's Sketchpad file is referenced, but no file exists within the resource
