Created to encourage open-ended building with minimal teacher involvement, our centre includes 8 photo cards showing actual buildings, plus tons of hands-on manipulatives that invite children to build, explore & engineer—again & again! For easy reference, the back of each photo card explains key elements for each design—so it’s easy to guide children’s learning. You get 130 geometric, interlocking plastic pieces and 8 photo cards. centre comes in an 11 1/2" plastic storage tub; longest building piece is 4".
