What does this painting have to do with math?
Piet Mondrian reduced his subjects to colorful geometric shapes. In this painting, bold, black horizontal and vertical lines frame the colorful squares and rectangles in red, black, yellow, and more. Do any of the shapes seem similar?
Do you notice that the smaller shapes are added together to create bigger shapes? How many shapes do you see in total?
