Presentations are modeled after the sequential learning process recommended by Dr. Montessori and supported by modern cognitive neuroscience: concrete experiences informed by mathematical reasoning leads to true abstract understanding. This fully developed set of concrete experiences requires nothing more than Golden Beads and a box of bead bars! And each experience uses mathematical and geometric reasoning to lead directly to abstract understanding.
Students who have completed even the earliest Montessori lessons in squaring and square roots will find these lessons fairly intuitive from the start. For students new to Montessori, the geometric principles are simple enough that they will catch on quite quickly.
