This colorful, educational stacking tower with 10 differently sized cubes can be stacked into a tower or placed side by side as a puzzle. Try to assemble the hidden puzzle by placing the blocks with the correct sides next to each other. The 5 sides are adorned with animals from around the world and numbers to teach children stacking, puzzling, counting, and recognition. A nice extra: 5 blocks have a cutout, allowing you to stack 2 blocks on top of each other. For example, place "Block 10" over "Block 9" to combine the habitat with the correct animal. This way, you can match the bamboo forest with the panda, the lion in the savannah, the toucan in the jungle, and so on. This allows the child to learn playfully which animal belongs where.
