All 4 pieces must be the same size.

The piece must be a corner piece.

A rectangle is divided into three vertical strips. The middle strip is much wider than the two side strips. If one of the narrow side strips is shaded, does this correctly show $\frac{1}{3}$?

Yes, because 1 of the 3 strips is shaded.

No, because the strips are not equal in size.

A circle cut into 6 slices, where some slices are bigger than others.

A hexagon (a 6-sided shape) divided into 6 identical triangles meeting at the center.
