| Full lesson | Create for a teacher a set of content for giving a lesson, beginning with the lesson plan. Each new block of materials must begin with an H1 heading (other subheaders must be H2, H3, etc). When you describe required pictures, write those descriptions in curly brackets, for example: {A picture of a triangle} |

This lesson aligns with the Australian Curriculum: Digital Technologies by introducing students to fundamental concepts of binary systems, enhancing their understanding of data representation in computing.
| Step Number | Step Title | Length (minutes) | Details |
|---|---|---|---|
| 1 | Introduction to Binary | 5 | Briefly introduce binary as a number system using only two digits (0 and 1). Explain its importance in computing. |
| 2 | Binary vs Decimal | 5 | Use examples to show how binary numbers work compared to decimal. Illustrate with simple numbers (e.g., decimal 2 is binary 10). |
| 3 | Conversion Activity | 10 | Provide students with handouts for converting decimal to binary and vice versa. Allow them to practice conversions in pairs. Facilitate assistance as needed. |
| 4 | Binary Arithmetic | 5 | Introduce binary addition (e.g., 1 + 1 = 10) with examples. Work through a few addition problems as a class using the whiteboard. |
| 5 | Review & Q&A | 3 | Recap key concepts covered in the lesson. Encourage questions and clarification on any topics discussed. |
| 6 | Homework Assignment | 2 | Assign students to practice binary conversions and simple additions at home. Provide them with online resources for assistance. |
Students are assigned to practice converting numbers between decimal and binary and to solve 5 binary addition problems. Collect assignments at the start of the next lesson for checking without presentations.
Informal assessment during the lesson through observations during group activities and understanding demonstrated in conversion exercises.
Encourage students to explore the historical context of the binary system and its foundational role in computer science. Provide optional extension activities for interested students.
