Look at KEVA from a whole new perspective with this interactive STEM tool! Brain Builders combines 20 KEVA boards with a set of thought-provoking puzzle cards. Each card has a 2D challenge on one side and its solution on the other. Your goal is to recreate 2D structures and turn them into 3D structures. The 2D cards show the design from different angles, emphasizing front, side and top views, and each increases in difficulty from beginner to expert. Manipulate the KEVA boards and successfully recreate the balance, proportion, composition and geometry depicted on each card. When you decide you have solved this technical drawing, turn the card over and check the solution - try to resist the temptation to peek at it prematurely. As each challenge becomes more complex, trial, error and retrying builds patience and confidence. From picnic tables and rafts to swans and snakes, you'll be amazed at what your brain can create! So test your 3D imagination and strengthen STEM, fine motor, strategic, physics and engineering fundamentals skills.
