It really reminded me of the educational 'toys' that I used while I was attending Montessori school. You could go at your own speed and come to understand a concept by letting you play with all the constituent parts when you felt like it - or if you saw someone else doing it and joined in.

One of the 'toys' I remember from my Montessori experience was these long bead chains. They had all different sizes, e.g. one would be a chain of 8 segments, each containing 8 beads on a rod between the joints. The '8' chain would be blue and have an associated blue cube of beads 8x8x8. I remember the '10' chain and cube was something really to be seen.

We also had really large blocks, because someone dropped one on my head.
