Those Danish are so stylish and savvy! Not only do they believe in ABCs as the building blocks (heh heh) of education, but they also recognize a fabulous computation opportunity when they see one.
Blocks with division signs and zeroes with lines through them? Yes, please! Plus, vividly colored blocks are just fun, whether they make mathematical and linguistic sense or not. Build a bridge! Make a pyramid! T ÷ 2 = skunk? Sure! Butterfly is greater than 9? You betcha! Just build, create, and enjoy.
