Train young brains to think in multiple dimensions with this interactive STEM tool! Brain Builders Junior combines 20 KEVA planks with a set of stimulating puzzle cards. Perfect for even the youngest of builders—each card features a fun, recognizable 2-D object and the goal is to recreate the pattern into a 3-D structure. The picture cards are numbered in order of difficulty—ranging from beginner to expert. Manipulate the KEVA planks to successfully duplicate the balance, proportion, composition and geometry featured on each card. With each build becoming more challenging, patience and confidence is gained through trial and error. From picnic tables and bridges to dragonflies and triangles, you will be amazed what your brain will build! Don't stop there! After mastering the 40 patterns, use your imagination to create your own designs or tackle the original Brain Builders! Brain Builders Junior teaches basic stacking techniques that can be put to use with larger KEVA construction sets. Recommended for ages 4 and up.
