Are These Two Parts Equal Halves?

Today I am practising: distinguishing two equal shares from two unequal parts
1
Draw a rectangle and divide it into two equal parts. Label each half.
2
Draw another rectangle and divide it into a very small part and a large part. Are they halves?
3
Fold a paper rectangle in half. How can folding help check equal shares?
4
Can two equal halves be made with a horizontal or vertical line? Try both.
5
If one half is covered, what fraction of the rectangle remains visible?
6
Explain why having two parts alone does not prove that each is one half.
- Use congruent rectangles for comparisons.
- Emphasize equal amount of the whole, not just two regions.
- Allow folding to establish equality before introducing fraction notation.
