Amusing and tricky tasks for playing with the classic Cuboro system! The aim of the tasks is to find a track course in which the marble runs from the first to the last element passing through all levels.
Book 3 is a collection of exercises - open-ended problems that will stretch your sense of 3-dimensional thinking and encourage creative problem-solving. This book will make a more imaginative and creative Cuboro builder out of even the most involved fan. The challenges it poses will give you a new way to think about Cuboro and marble runs.
Great for play, Montessori educators and homeschoolers.
