Picking the right CS Fundamentals course for your classroom
With the diverse set of options offered for CS Fundamentals, there is a course for all different needs.
How will your students engage with the content?
Courses specifically designed for your elementary classroom
Find the course for the grade you teach. Each course is approximately a month long.
Kindergarten
Course A
Program using commands like loops and events. Teach students to collaborate with others, investigate different problem-solving techniques, persist in the face of challenging tasks, and learn about internet safety.
Grade 1
Course B
Through unplugged activities and a variety of puzzles, students will learn the basics of programming, collaboration techniques, investigation and critical thinking skills, persistence in the face of difficulty, and internet safety.
Grade 2
Course C
Create programs with sequencing, loops, and events. Investigate problem-solving techniques and develop strategies for building positive communities both online and offline. Create interactive games that students can share.
Grade 3
Course D
Review of the concepts found in earlier courses, including loops and events. Afterward, students will develop their understanding of algorithms, nested loops, while loops, conditionals, and more.
Grade 4
Course E
Make fun, interactive projects that reinforce learning about online safety. Engage in more complex coding such as nested loops, functions, and conditionals.
Grade 5
Course F
Look at how users make choices in the apps they use. Make a variety of Sprite Lab apps that also offer choices for the user. Learn more advanced concepts, including variables and “for” loops.
Self-paced elementary curriculums
Teachers play a critical role in student learning by teaching our unplugged activities and leading whole class discussions, however, we recognize that CS Fundamentals isn't always taught in a traditional classroom setting. We provide two self-paced express courses alongside Courses A-F. These express courses are designed for situations where teachers allow each student to work at their own pace independently.
Grades: K-1
Pre-Reader Express
Learn the basics of drag-and-drop block coding by solving puzzles and creating animated scenes. Make art and simple games to share with friends, family, and teachers.
Grades: 2-5
Express
Learn to create computer programs, develop problem-solving skills, and work through fun challenges! Make games and creative projects to share with friends, family, and teachers.
No devices? We have you covered
Go ahead, cut the cord (for a while)!
CS education does not always need to be in front of a screen and device access shouldn't be a barrier to learning computer science concepts.

Frequently asked questions
Is CS Fundamentals mapped to standards?
CS Fundamentals was written using both the K-12 Framework for Computer Science and the CSTA standards as guidance. Currently, every lesson in CS Fundamentals contains mappings to the relevant CSTA standards. The summary of all CSTA mappings for each course can be found at:
- Course A Standards
- Course B Standards
- Course C Standards
- Course D Standards
- Course E Standards
- Course F Standards
A Google Sheets version of the standards can be found at CSF Standards.
How can I bring CS Fundamentals to my whole school?
The leading K-12 CS curriculum in the United States, our elementary program has been proven effective in major urban school districts like Dallas, as well as small rural districts in Iowa. There is no need to hire specialists to teach CS. Our program is uniquely designed to support teachers new to CS while offering the flexibility to evolve lessons to fit student needs. Share this brochure with your school and district administrators, or suggest they take a look at our administrators page specially designed to answer administrators' most common questions.
How much does it cost to teach CS Fundamentals?
Our curriculum and platform are available at no cost for anyone, anywhere, to teach!
How/Where can I get professional development for CS Fundamentals?
New to teaching computer science? No worries! Most of our teachers have never taught computer science before. Join local teachers for inspiring and hands-on support to implement computer science in your classroom. Our Regional Partners offer high-quality, one-day Code.org workshops for individual teachers or for schoolwide PD. Sign up for a professional development workshop near you!

What is the recommended timing for teaching CS Fundamentals?
Each CSF course includes 13-17 lessons designed for 45-minute periods. We recommend all students move from lesson to lesson at a pace set by the teacher. There are many teacher-led project levels designed to be experienced in unison while the skill-building lessons can be completed by students at their own pace.
What materials do I need for CS Fundamentals?
Many lessons have handouts that guide students through activities. These resources can be printed or assigned digitally. Some lessons call for typical classroom supplies and manipulatives. Visit the CSF Syllabus to learn more.
