M2.4.1 For the adult
Fair shares: equal parts
My brother cut the bread in two. Is his piece really a half?
What this chapter teaches
A fraction starts with equal parts. Pieces only count as halves, thirds or quarters when they are the same size, however they are cut.
Three questions to ask
There is no one right wording. Listen for the idea.
- How can you tell whether two pieces of bread are halves?
- Is it fair when one person gets 6 beans and another gets 4, and why?
- Can you show me two different ways to cut a square into 4 equal parts?
After the chapter, the learner can
- Tell if a shape is cut into equal parts
- Share a group of things fairly between 2, 3 or 4 people
- Explain why two pieces of different sizes are not halves
What they copy into their notebook
Equal parts are the same size. A half is one of two equal parts. Two pieces are only halves if they are equal.
