Exploring Reasoning and Proof
  Introduction | Try It Yourself: The Frosted Cube Cake | Problem: Math Banquet | Solution: Math Banquet | Verifying the Problem Algebraically | Problem Reflection | Your Journal

 
 

You've just explored two problems and examined how you might reason about them. Now we'd like you to write about your own classroom practice. As you make your journal entry, use the material you've just seen and read as a context.


Questions to write and reflect about:
  • Do you present problems like these in your classroom? What are some characteristics of problems that are worthwhile mathematical tasks and that encourage students to sharpen their reasoning skills?
  • Middle school students should expand the audience for their mathematical arguments beyond their teacher and classmates; how can you help them achieve this?
Three ways to write and reflect:
  • Use pen and paper.
  • Use a word processor.
  • Use the form below.
Be sure to save what you have written before you navigate out of the journal section.
