- A whole can be represented as a sum of unit fractions based on how it is partitioned.
Essential Questions
- How can you divide a shape into equal areas in more than one way?
- What does it mean for a part to be a unit fraction of a whole?
- Can equal shares have different shapes? Why or why not?
- How does dividing a figure into equal areas help us understand fractions and area?
- Why is it important to recognize equal shares when their shapes are not the same?
