Lego Coding Express

Lego Coding Express STEM Kit contents

Inspire early learners to explore early coding concepts such as sequencing, looping, and conditional coding, while developing problem solving skills, critical thinking, collaboration, and social and emotional skills.

Make the train pause, stop, change direction, sound the horn, and more! Taking the familiarity of a train and combining it with the new action bricks, early learners will learn through play about sequencing, looping, conditional coding, and cause and effect by placing the new action bricks within the train’s track. Each action brick creates a specific action allowing for students to test and redesign ways to problem-solve and work together to get their train to its destination.

The free optional app combines physical play with digital intervention and is designed to enhance the experience. When you introduce the app, the 4 different themed activities change the way the action bricks behave, altering the effect on the train.
