Personal annotations
Yehudi Menuhin, a great violinist, marked up a score for Bach's Sonata No. 2 for Solo Violin. Penciled annotations show real-time performance strategies. To outsiders, insider markups appear chaotic and cryptic, but these personal annotations are for Menuhin's eyes, the only eyes that matter. All can learn from this useful workaday grid strategy: a relevant and intense data layer can become a coherent substrate scaffold upon which to overlay additional information. Maps do this all day long.
Gifts and occupations
Between 1835 and 1850 Froebel worked on his “Gifts and Occupations” — a set of geometric blocks (Gifts) and basic craft activities (Occupations), that would become the centerpiece of his pedagogical theory. The Gifts and Occupations were introduced in a highly ordered sequence, which began in the child’s second month and concluded in the last year of kindergarten.
