Lesson Title:
Binary and people, vs binary and computers.
Duration:
1 hour
National Curriculum Targets met:
1. Develop their capability, creativity and knowledge in computer science
2. Develop and apply computational thinking skills
TIMING ACTIVITY
Learning Objectives:
• To understand that human gender is not binary.
• To understand that computers use binary language to function, and to be able to add binary.
5 mins By the end of the Lesson:
All students must; Be able to add 4 binary numbers, understand that human gender is not binary.
Most students should; Add 8 binary numbers and be able to explain the words which describe different genders
Some students could; Explain the overflow error when adding binary.
KEYWORDS
Transgender = a person whose self-identity does not conform with the sex they were assigned at birth
Binary = Classification of gender into two distinct
forms of masculine and feminine

Activity 1: Why is human gender not binary?
Look at different people and how they identify. Why is it important?
Review and apply
Activity 2: Why do computers use binary? Adding
binary – learning the rules
Looking at overflow.
Activity 3: Converting binary numbers to decimal
Review and apply
Support the learning – Differentiation:
Where appropriate, identify students and the methods of support and extension to be used
Task for students who need support:
Addition sheets with some answers given.
Task for students who need extension work
A number with overflow
Celebrate the Learning - Plenary:
Students demonstrate in some way what they have learned. Recognition of progress. Refer back to Learning Objectives.

Review what learnt about how to work with binary code.
To compare computers to human beings – people so much more complex, not binary.
Look at Josie’s experiences and discuss what was key to ensuring she could be happy.
