The study group moved on to playing with surface area and how to enclose the most amount of space using all eight blocks in a set of Gift 4. They discovered they could enclose 12 squares on the grid by making a rectangle.
Bob enlarged his interior space to 16 squares by forming the blocks into a square. While the others were busy copying his square, he arranged his blocks, corner to corner, into an eight-sided shape and enclosed more than 16 squares.
They did a bit of transformations of beauty forms, which has everything to do with symmetry, whereby the method of transformation from one design to another entails moving one block at a time (at most two) , then its opposite block(s) all the same degree in relation to and around the center of the patterns, as illustrated from left to right.
