Lego Decomposition

For my year 4-6 classes I created a number of models as shown below.

Students were then invited to pair up. They were given a picture of the model, the blocks to be used to create a model, and the instructions and rules below.

Students had to sit back-to-back, one student had to decompose the instructions, while the other student built from the instructions given.

This is a very challenging task that tests understanding and the ability to decompose instructions.

    This also calls for well developed oral language of the engineer to verbalise the instructions clearly and active listening for the builder to hear and process these instructions. Great ideas.
