This is the second manual in the Combined Levels set. It is the composite of the Primary and Elementary Levels Yellow Books. Besides the skills of attention, memory and problem-solving, the student is required to reproduce two-dimensional designs onto a geoboard. The importance of an adult, or guide, working through this process with the student is critical and makes this one of the few programs which utilize motor skills as well as a mentor working with the student as the challenges are completed.
