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.

binary – learning the rules

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.
