CodeBytes: 20 minute, mini-lessons for all ages

Planning for the Hour of Code with your classroom that’s gone virtual? Try a CodeByte! Designed to fit smoothly into a distance learning plan, CodeBytes are easy-to-digest, 20 minute interactive lessons that will stream during Computer Science Education Week, December 7-11.

We saw how many people loved taking a Code Break earlier this year. So, we’re packaging up that CS goodness into 5 different fun-sized CodeBytes during the week!

Every episode features a new lesson that blends computer science with real-world topics. One day, students will use Dance Party to get creative and express themselves. Another day, they’ll explore environmental sustainability with Artificial Intelligence.



While our live episodes have already taken place, you can still view the recordings and try the activities.

CodeBytes are great for:

  • Students with varying access to technology. Participants can tune-in and interact whether they have a laptop, tablet, or smartphone!
  • Young students who may not be ready for fully self-led Hour of Code activities.
  • Older students who want to engage in a group lesson.
  • Parents and caretakers looking to supplement their child’s learning at home.
  • Educators looking for a simple, pre-planned way to bring the Hour of Code to their virtual classrooms.
  • Stay in the know! Join our mailing list to receive Code.org updates and be the first to learn of new resources for at home learning.

    Follow us on Facebook or on Twitter.

    Lessons are created and led by our very own Code.org staff, many of whom were teachers themselves previously! This means you don’t need any additional resources or lesson plans in order to organize a fun and educational Hour of Code event to your class even when they are participating from home. All you and your students have to do is tune-in!
