The document shows 4 squares - A, B, C, and D where 1/4 of each square is shaded. It asks to divide the unshaded portions of each square into an increasing number of equal parts without using triangles: square A into 2 parts, square B into 3 parts, square C into 4 parts, and square D into 7 parts. It provides clues that the solution is in the problem itself and the world record to solve it is 7 seconds, as this is a lesson about mindset.
