 Exploring Communication
 Introduction | Problem: Shaded/Unshaded Circles | Solution: Shaded/Unshaded Circles | Talking About the Problem | Representing Fractions with Rods | Other Denominators | Modeling Operations | Try It Yourself: Cuisenaire Rods | Problem Reflection | Summary | Your Journal
 Think about how you used Cuisenaire Rods to solve the previous problems, and answer one or two of the following questions: How would you explain your thinking to someone who had little experience with the Cuisenaire Rods model for fractions? This problem is an example of a particular concept - operations with fractions -- that can be difficult to learn. Using a variety of strategies and materials allows us to communicate about this concept in different ways. What are two strategies for adding and subtracting fractions that are different from those you currently use? How do the rods encourage discussion about common multiples and the operations of addition and subtraction?
