The mother of all building block sets is the Kapla 1,200 piece Wooden Building kit. Kapla (“pixie planks” in Dutch) has been in the business of sparking imaginative play for many years now, with these simple rectangles of wood manufactured from 100% natural pine sourced from renewable forests in France. Kapla insists that the special design, based on a 1:3:5 ratio, is perfect for enhancing “confidence, curiosity and determination.” If you’re daunted about what to do with 1,200 pieces of wooden fun, the sets are also available in more manageable 40 piece kits.

+ Kapla (40 piece set) $29.95 (1,200 piece set) $389.95 at Glamma Toys.
