TYC contributor Laura Colker answered this question in an online Q&A* about the value of creating a construction focused learning center in a primary classroom, and how to explain its importance to an administrator.
The key to approaching an administrator who may question how Legos, blocks, and other building materials fit into the curriculum is providing clear examples of the ways a construction learning center can inspire and enhance academic learning. To do this, focus on the clear link between construction and STEM (Science, Technology, Engineering, Math) learning. It is generally agreed that to be competitive in our global economy children need to develop learning and skills in science, technology,engineering, and mathematics. Building with blocks, Legos, and other building materials can connect to STEM learning in many ways.
