Translators (Compiler & Interpreter)
👩🏫 Teacher’s Guide
Objective
Students will explain that translators convert code into a form the computer can run and compare compilers and interpreters in simple terms.
Teaching Notes
- Keep it simple: computers understand machine code; translators help.
- Compiler translates a whole program; interpreter translates line-by-line.
- Use language analogy: translator helps people understand each other.
- No need for specific languages; focus on concept and purpose.
🧒 Student Worksheet
Concept and Helping Material
Computers do not understand human languages like English. They understand machine code. Translators help convert code into something the computer can run. A compiler translates the whole program, while an interpreter translates one line at a time.
Computer Vocabulary and Definition
- — A tool that changes code into a form the computer can run.
- — A translator that converts a whole program at once.
- — A translator that runs code line-by-line.
- — The language computers understand.
- — To make a program work and perform actions.

Computer Prtactices
- Translate analogy: Write how a language translator helps people communicate.
- Compiler vs interpreter sort: Match statements to the correct translator type.
- Error spotting: Read 3 simple ‘code’ lines and circle the one with a mistake.
- Flow diagram: Write steps: write code → translate → run → see output.
