Do arithmetic with a smooth hand! These finely painted stacking owls made of lovingly detailed wood want to go up, up and away. They can be used to build pyramids, towers or impossible works of balancing art in various formations or according to the numbers. There are fine matching notches on the wings, feet and head in which the happy birds can be stacked on top of each other. If the two wooden poles are included in the game, the difficulty increases. The young stackers will train their concentration and fine motor skills while gaining a feeling for balance and gravity. These owls are great for experimenting, adding, and so on and so forth - a game that puts you in a great mood!
