Computer Science

Computer Science — Grade 4

American Curriculum · Ages 9-10

Fourth grade computer science introduces variables — a way to store and change information such as a score, a timer or a name. Students combine variables with loops and conditionals to build genuinely interactive projects, and plan on paper before they code.

They also learn how computers represent information, what a network is, and how data travels across the internet. Digital citizenship covers digital footprints, respectful communication and recognizing misleading content.

Key topics covered

• Variables — Storing and changing values such as scores, timers and names.
• Program Design — Planning a program's structure before writing any code.
• Combining Constructs — Loops, conditionals and variables working together in one project.
• Networks & the Internet — What a network is and how information travels between devices.
• Data Representation — How computers store text, numbers and images.
• Digital Citizenship — Digital footprint, respectful communication and misleading content.
