After building a Colonnade and Cube (Box) per the Kindergarten Guide, each player made a Stoop. Christi assembled the steps according to a mathematical sequence, subtracting a half step, or 1/2 of the width, for each step. It is the one in the middle.

Christi mentioned how musical intervals also have a pattern of the whole steps and half steps. Otherwise, the players constructed the sides of the Stoop as shown in the guide book. It takes very careful observation to copy exactly!
