Welcome to teach123.vex.com!

Welcome to teaching with VEX 123! VEX 123 is specifically designed to help anyone bring computer science to life for their students, no matter what experience they have with robotics. Whether using VEX 123 in a learning center, as part of a math lesson, in a STEM class, or in an after-school club, there are materials that make it easy for you to get started teaching with VEX 123 in any setting. This page is a hub of resources that you can use as you begin teaching with 123, and return to later to learn more. Educators’ plates are more full today than ever before, often with more questions than answers. This page is here to help you take the guesswork out of teaching with VEX 123, and to be a support on your STEM teaching journey. 

“VEX 123 was so approachable that even with no prior experience, I was able to start teaching with the robot right away. My students loved their robots from day one! Over time we all learned about coding together, and more importantly, I found that I could take the fun and excitement of using the robots to help students practice other skills and subject matter also. So it has been a win-win experience for the whole class!”

Getting Started is Easy!

While VEX 123 can be used to teach computer science, it can also be used to infuse computer science concepts into your existing curriculum. Using the 123 Robot to reinforce subject area concepts and skills is a way to capitalize on the engagement and motivation that the robot brings to classroom activities. VEX 123 curricular resources offer a variety of subject area connections to help you bring 123 into your classroom in ways that best meet your students’ needs and interests.

VEX 123 curricular resources offer a variety of subject area connections to help you bring 123 into your classroom in ways that best meet your students’ needs and interests.

Activities, Activity Series, and STEM Lab Units offer growing levels of teacher support and scaffolding. Activities are simple enough for independent student use; Activity Series build on Activities with some Teacher Notes about the setup; and STEM Lab Units are like an online teacher’s manual with a wealth of embedded planning and teaching resources.

Scope and Sequences to get started


Learn as You Go: Train and Teach in Tandem

VEX offers free, online, hands-on, self-paced Educator Certifications for all platforms. These trainings enable teachers to learn about the products as well as the teaching resources that support them.

However, you do not have to be certified in order to begin teaching with VEX 123! You can train and teach in tandem, and directly apply your certification progress to your classroom on a week-by-week basis.

Want training while you teach?

The ‘Learn as You Go Scope and Sequence’ will enable you to engage with the VEX 123 Certification in preparation for teaching lessons connected to each Unit. Over the course of 9 weeks you will work through the training course as you teach, so that you can directly apply your learning to your teaching practice.

Looking for more than training?

Pair the Certification with PD+ features to make the most of your professional development journey. The ‘Learn as You Go with PD+ Scope and Sequence’ adds a PD+ component to the ‘Learn as You Go Scope and Sequence’ so you can take your learning even further as you teach with VEX 123.


Differentiation Made Simple

One lesson, taught three ways

The three methods of coding with VEX 123 – Touch buttons, the Coder and Coder cards, and VEXcode 123 – not only raise the ceiling of the kinds of coding that can be done with the 123 Robot, they also provide educators with great flexibility in how they teach with VEX 123. The same STEM Lab or Activity can be taught across multiple grade levels by adapting the coding method that is being used. Similarly, students within the same class can complete the same activity using the coding methods that best meet their individual needs and developmental levels.

VEX Coder and Coder Cards lend themselves to differentiated instruction

When using the VEX Coder and Coder cards with the 123 Robot, the teacher is able to control the commands that students have access to while building their projects. This flexibility gives teachers the opportunity to offer different commands to different groups in order to best meet students’ needs and scaffold their learning appropriately. All students in a class can work on the same coding activity, yet use different commands to do so. Not only does this enhance students’ engagement by keeping them suitably challenged, it helps them see firsthand how there can be multiple ways to solve the same problem—an important habit of mind for young learners.

Grow your teaching and learning as your students' capacity for coding grows. Begin with Touch buttons, grow to coding with the Coder and Coder cards, then expand to coding with VEXcode 123. VEXcode 123 gives an opportunity to build upon what students have learned through device-free, tangible coding methods to a block-based platform that offers a wealth of coding opportunities and challenges. 


Making Learning Visible

We cannot always rely on our students to paint an accurate picture of what they are learning and doing at school to their families or those outside our classrooms. As such, it is important for teachers to show evidence of learning on their walls, in communications with families, and through artifacts that can be shared with those inside and outside the classroom. You can communicate what students are doing and learning with VEX 123 with your community quickly and easily using these built-in resources.

Letters Home foster participation

Each STEM Lab Unit Overview includes a unit-specific Letter Home that gives families a window into the activities and learning their students are doing with VEX 123 at school. The Letter Home is an editable Google Doc that can be tailored to best meet the needs of your community, making it easy for you to add or remove information, translate the letter into additional languages, and include photos or other artifacts of student learning. All Letters Home include the following sections:

  • Introduction - sets the stage for the STEM Lab Unit and explains the big questions that students will be exploring throughout the labs
  • Look Inside the VEX 123 STEM Lab Unit - explains the activities in each Lab that students will be working on with their robots to explore the topic
  • Vocabulary - offers general information about the purpose of vocabulary words in relation to students’ learning and a list of words that are relevant to the Unit
  • Connection to Daily Life - explains connections between the kinds of things students are doing and learning and everyday occurrences and experiences that families can talk about and share with their students
  • Follow up questions to ask at home - gives families ‘dinner table’-style questions that they can use to help students talk about their experiences with VEX 123 to further build the home-school connections that support their learning
  • Computer Science Starts Early with VEX 123 - offers a glimpse into the research-backed pedagogy that supports teaching and learning with 123

The Letter Home can be found in the Unit Overview of each STEM Lab Unit. View the video to see where the Letter Home is located within a STEM Lab Unit.

Teaching with Activities or Activity Series? This general Letter Home can be used to give families an idea of the kinds of things their students will be doing and learning.

Printables and posters show learning

Teacher teaching students how to use VEX 123 on white board

VEX 123 Posters and Printables can help paint the picture of how you are engaging with robotics and computer science in your classroom. Just as we have posters for other subject areas, VEX 123 provides posters that communicate that coding is part of your learning to anyone that enters your classroom. Using a poster to anchor a learning center, as part of a VEX 123 bulletin board, or as a hallway feature gives visibility to what you are doing and can be a conversation starter for classroom visitors.

Additionally, VEX 123 Printables offer paper and pencil worksheets and manipulatives that you can use to support planning and saving of student projects. Completed printables can be saved and used as part of a student portfolio, included in parent-teacher conferences, or hung on a VEX 123 bulletin board. Having printed projects accessible for students gives them a way to revisit their own and classmates’ experiences as their knowledge grows.
