Skills
- explain (relationship between number of fractional parts and size of each part) #dok2
- compare (sizes of fractional parts of a whole) #dok2
- analyze (how changing the number of fractional parts affects their size) #dok3
Learning Targets
- I can explain how the size of each part changes as the number of fractional parts increases. #dok2
- I can compare parts of a whole when it is divided into different numbers of equal parts. #dok2
- I can analyze and describe the relationship between the number of fractional parts and their size using models or drawings. #dok3
Big Ideas
- The size of each fractional part depends on the number of equal parts that make up the whole.
- Dividing a whole into more equal parts makes each part smaller; dividing it into fewer parts makes each part larger.
Essential Questions
- What happens to the size of each part when a whole is divided into more equal parts?
- How does the number of parts affect the size of each fractional part?
- Why is a fourth smaller than a half?
- How can you use objects or pictures to show that more parts make smaller pieces of a whole?
- What are some real-life examples of dividing an object into different numbers of equal parts and comparing their sizes?
