Question 6 – Equal parts on a grid [2 pts]
The rectangle is made of 18 equal squares. Draw lines to cut it into 3 parts with equal area. What fraction of the rectangle is one part?
Question 7 – The cut square [2 pts]
A square napkin with sides of \(8 ext{ in}\) is cut by a straight line from one corner to the middle of the opposite side. Aisha says the shaded triangle is \(\frac{1}{2}\) of the square because there are 2 parts. Is she right? Explain.

- Explain your answer to part b. (1 point)
Question 9 – Two cuts [2 pts]
A square is cut into 4 parts with equal area. Maya cuts hers into 4 small squares. Jamal cuts his into 4 triangles. Do both children have fourths? Explain.
