Children get a hands-on introduction to STEM as they replicate real-world designs—from simple train tracks to a towering skyscraper! Kids just look at the photo on an inspiration card and balance wooden planks on top of each other to build a mini airplane, bed, bridge and more—no glue, screws or snaps needed. Set includes 100 planks with smooth, rounded edges...plus 15 double-sided cards that each feature a challenge on front and a possible solution on back. Cards measure 8" x 8" and are colour-coded by level of difficulty. Develops skills in fine motor control, structure and stability, balance and gravity, and creative design.
