Implementing VEX 123 STEM Labs

STEM Labs are designed to be the online teacher’s manual for VEX 123. Like a printed teacher’s manual, the teacher-facing content of the STEM Labs provides all of the resources, materials, and information needed to be able to plan, teach, and assess with VEX 123. The Lab Image Slideshows are the student-facing companion to this material. For more detailed information about how to implement a STEM Lab in your classroom, see the Implementing VEX 123 STEM Labs article.

Goals and Standards


Students will apply

  • The use of features and functions to control the 123 Robot in future labs and explorations.

Students will make meaning of

  • How a robot is different from other devices that they know and use, because it can sense, plan, and act.

Students will be skilled at

  • Matching a function with its feature on the robot in order to create behaviors.

Students will know

  • The 123 Robot is a mechanical device that can carry out an action when programmed by a human. 



  1. Students will identify the basic features and functions of the 123 Robot components with appropriate terminology.


  1. Students will be introduced to each individual feature of the 123 Robot in a story-based guided introduction in the Engage section. In the Play sections, students will further explore and identify each feature through facilitated exploration.


  1. Students will identify the 123 Robot parts and complete a features chart that catalogs each feature, its name, and what it does in the Share Section of the Lab.
