The complete set of Experience CS units is now available.

With the release of the final six units, Experience CS now provides 18 cross-curricular, project-based computer science units for grades 3–8. It offers educators a collection of free, standards-aligned units to bring computing into their classrooms with confidence.

This milestone marks the culmination of a year of development, iteration, and collaboration with educators. The result is a set of learning resources designed by educators for educators, for real classrooms and real teaching needs.

What is Experience CS?

Experience CS is built to make computer science (CS) accessible, engaging, and relevant for all learners, and teachable for all educators.

Rather than treating CS as a standalone subject, Experience CS integrates computing into core subjects like science, math, and the arts. Students learn key concepts such as sequencing, loops, cybersecurity, and networks while exploring meaningful, real-world themes. The Experience CS platform includes a school-safe version of Scratch that is easy for teachers to use and where students can explore making coding projects.

Every Experience CS unit includes:

• Ready-to-use lesson plans
• Slides and teaching resources
• Student activities and starter Scratch projects
• Step-by-step teacher guidance

No prior computer science experience is required — Experience CS makes it easier than ever for schools to get started.

From launch to completion

Since we launched Experience CS in June 2025 with the first 6 units, we’ve worked steadily to create more resources, guided by feedback from educators and classroom testing.

Now complete, Experience CS offers:

• A fully scaffolded learning experience for students aged 8–14
• 18 classroom-ready units
• 3 units per grade level (Grades 3–8)

Along the way, we have also added:

• Unit 0: Getting started, introducing Scratch and the Code Editor for Education platform
• Spanish and French translations, broadening access for more learners
• Updates informed by teacher feedback

What are the newest units about?

The final Experience CS units give students more opportunities to create, explore, and apply their learning:

• Unit 3.3 — Like, literally? Bring figurative language to life! Students animate an idiom in Scratch, use code to check user guesses, and create an interactive project that reveals the meaning behind the words.
• Unit 4.3 — Logic and lore: Design a hero and build a survival game! Students determine character stats, create power-ups, and use code to determine their character’s fate.
• Unit 5.3 — What are the odds? Can a program predict your future? Students build a yes-or-no response generator, explore how data is stored, and test whether their program’s predictions match real-world results.
• Unit 6.3 — Under the sea: Discover how messages travel across the world! Students explore networks, packets, and error-checking, then create an interactive program that tells the story of digital communication in action.
• Unit 7.3 — Cipher quest: Crack codes and design your own digital escape room! Students explore ciphers, build secure password systems, and use programming to hide and protect secret information.
• Unit 8.3 — Art all around: Use code to create stunning abstract art! Students design algorithms, transform shapes, and build programs that turn mathematical ideas into original works of art.

What’s next for Experience CS?

While the curriculum is now complete, our work to expand access is just getting started.

Events and professional development

Throughout 2026, we will host sessions, workshops, and conference events to support educators across the US in bringing Experience CS into their classrooms. These free professional development opportunities will help teachers build confidence, explore best practices, and connect with a growing community of educators.

We will host a webinar on April 30 at 3pm CT / 4pm ET to highlight the new units. Register today to join:

And you’ll find us at the following events this spring and summer:

• ASU+GSV Summit: April 12–15, 2026 in San Diego, CA
• MCTM Spring Conference: April 23–25, 2026 in Duluth, MN
• CS Con: June 16–18, 2026 in Georgia
• CSTA Annual Conference: July 13–15, 2026 in New Orleans, LA

And more! Keep up with us on social media to stay in the loop with conference appearances and sign up for Experience CS mailing updates to hear about upcoming PD opportunities.

Supporting adoption in schools

Experience CS is already being implemented in schools and districts across the United States. With Data Privacy Agreements (DPAs) now in place in multiple states, even more districts can adopt the curriculum.If you have any questions about DPAs or district expansion, please reach out to experience-cs@raspberrypi.org.

A milestone for integrated computer science education

The completion of Experience CS marks a big step forward in making computer science education accessible, creative, and inclusive.

The cross-curricular design of each unit empowers non-specialist teachers to confidently introduce computer science in their subject and help students connect it to the world around them.
