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
