LEGO-Based Therapy is a social and communication intervention that uses LEGO activities to support the development of a wide range of social skills within a group setting. It can be used to target goals around social skills, language and motor skills. Furthermore it supports self-esteem by allowing the participants to demonstrate their skills in a social situation. It also sets up a positive opportunity for guided social problem-solving to help develop social skills that can then be used in other situations.

During a LEGO-Based Therapy session, three children work together to build a LEGO model following.

Each child takes on one of three specific roles to do this:

• The Engineer oversees reading and relaying the instructions. The Engineer must tell the Supplier what pieces to retrieve and tell the Builder how to build the model.
• The Supplier oversees finding the correct LEGO pieces. The Supplier must listen to the Engineer and figure out what piece to retrieve, and then given these pieces to the Builder.
• The Builder oversees physically building the model. The Builder must listen to instructions provided by the Engineer and receive the pieces that are retrieved by the Supplier.

Using this format provides each child with an opportunity to practice and develop a wide range of skills, including language skills (in both giving and receiving instructions) turn-taking, negotiating, sharing and collaborative social problem-solving. It also encourages children to reflect on their own actions and skills as well as give constructive feedback to their peers.
