Welcome to HABA's Clever Up! Building System. Building blocks help children to fulfill two natural needs: imitating the grown-ups and constructing things. This is how children familiarize themselves with the adult world. Children use the building blocks to playfully shape the space around them and at the same time begin to grasp the concept of the third dimension. Through constant repetition and trial and error, they also acquire an empirical understanding of the laws of physics.

Through constant repetition and trial and error, they also acquire an empirical understanding of the laws of physics. Cubes, baseplates and slats are the basic elements used in construction, bridging and the addition of ramps and floors. Younger children study the available blocks before lining them up and stacking them. Later on, they create more complex patterns and even more grandiose buildings. 46 piece set includes: 24 cubes, 8 baseplates (in two lengths) and 14 strips (in three lengths). Includes educational booklet and cotton bag. Standard Unit Block Cube dimensions: 1.75" x 1.75" x 1.75". Cleaning Instructions: Use a cloth dampened with warm water. You may use a small amount of dish soap or vinegar essence mix combined with water. Both work extremely well in destroying bacteria and cleaning wooden toys. Do not submerse in water or place in dishwasher. Disinfectants (even organic baby wipes) should not be used as they can damage the water based coatings that protect the colorful stains & paints beneath.
