Sample Problem

Making Connections, Course 1:  

Trail Mix 1-27. TRAIL MIX

Rowena and Polly were making trail mix. Rowena had 4 cups of raisins, and Polly had 4 cups of peanuts.
Polly poured exactly one cup of her peanuts into Rowena's raisins and stirred them up, as shown in the diagram at right. Then Rowena poured exactly one cup of her new peanut-and-raisin mix back into Polly's peanuts.

Did Rowena get more of Polly's peanuts, or did Polly get more of Rowena's raisins?

Your task:

  • First decide by yourself what you think the answer to this question is.
    Then share your ideas with your team.
  • Together make a guess (also called a conjecture)
    about which girl got more of the other's snack item.
  • Explain your conjecture with words, numbers and symbols, diagrams, models, or anything else you think will convince another student.
