WDS kindergarten, first and second graders spent Chol Hamoed at Westchester Day School using their engineering skills to build sukkahs out of LEGO, cardboard, and classroom materials. Students were introduced to special cardboard tools from Makedo, including child-safe cardboard saws, screws and screwdrivers. They also learned that cardboard is made of three layers of paper glued together with a special adhesive. Check out their amazing designs!
