What is Lego® Therapy?

What is Lego® Therapy?

Lego® Therapy is a therapeutic intervention that is designed to support children and young people with autistic spectrum disorder (ASD), social communication difficulties and language difficulties.

The purpose of Lego® Therapy is to help children to:

  • Ask questions
  • Initiate communication
  • Develop eye contact
  • Repair communication breakdowns & seek confirmation
  • Use descriptive language
  • Develop turn-taking skills

These skills are essential in order for successful communication to take place.

The current evidence suggests that children and young people who attend Lego® Therapy groups develop skills in these areas and generalise these skills to other environments (e.g. classroom, home, playground).

What does Lego Therapy involve?

Lego® Therapy groups are typically run by a Speech and Language Therapist who works with children in groups of three. The children are each given a different role and need to work together to build the Lego® model. The three job roles are:

The Engineer

The engineer tells the supplier which Lego® pieces are needed & then tells the builder how the pieces should be put together.

Skills needed:

  • The engineer needs to be able to describe the pieces needed
  • The engineer needs to use prepositional language to tell the builder where to put the pieces
  • The engineer needs to be able to reword or rephrase his/ her instructions if the supplier or builder haven’t understood them
  • The engineer needs to be be able to take turns with others and be able to problem solve

The Supplier

The supplier gives the Lego® pieces to the builder.

Skills needed:

  • The supplier needs to be able to understood what the engineer is saying to them
  • The supplier needs to be able to repair a conversation breakdown (e.g. what will they do if they don’t understand the engineer?)
  • The supplier needs to be able to take turns with the engineer and the builder
  • The supplier needs to have good listening skills

The Builder

The builder listens to the engineer and puts the Lego® pieces together.

Skills needed:

  • The builder needs to be able to understand what the engineer is telling them
  • The builder needs to be able to ask for help/ clarification if they don’t understand
  • The builder needs to be able to take turns and to work together with the supplier and engineer.

These roles are rotated during each session so that each child/ young person gets a chance to do each job. The Speech and Language Therapist will support each child/ young person to develop their individual skills. The Speech and Language Therapist will record each child’s/ young person’s progress in each of the skill areas in order to track progress.
