OCR GCSE Computer Science – Lesson 1: Introduction to Boolean Logic (TRUE/FALSE, AND/OR/NOT) – Full

A complete first lesson for OCR GCSE Computer Science introducing Boolean logic, binary decisions, and TRUE/FALSE values. This resource is perfect for starting the Logic & Algorithms strand of the OCR J277 Computer Science specification.

The lesson is ready to teach with no planning required and includes an editable PowerPoint and a structured student worksheet booklet.

Designed for the OCR J277 Specification

This lesson directly supports OCR GCSE Computer Science Component 2:
2.1.3 – Boolean logic – truth tables, simple logic diagrams, and Boolean expressions.

Students are introduced to Boolean values and expressions before moving on to more complex logic in later lessons.

What’s Included
Lesson PowerPoint (PPTX – editable)

Covers everything required for an OCR introduction to Boolean logic:

What Boolean values are (TRUE/FALSE, 1/0)

Why computers use binary logic

AND / OR / NOT explained with examples

Real-world Boolean uses (search engines, circuits, programming)

Interactive “How is Boolean used here?” tasks

OCR-style exam prompts

Embedded tasks + plenary

Student Worksheet / Workbook (DOCX – editable)

Your worksheet contains:

Starter (True/False misconceptions check)

Key definitions recap

Structured questions

Boolean expression problems

Real-world scenarios to convert into Boolean statements

Exam-style questions for OCR

Challenge section for high-ability learners

Self-assessment checkpoints

Perfect for classwork, revision, or homework.

Learning Outcomes (Aligned with OCR)

By the end of the lesson students will be able to:

Define Boolean values and binary decisions

Recognise TRUE/FALSE and 1/0 representations

Understand why computers rely on Boolean logic

Apply AND, OR, and NOT to build expressions

Solve Boolean reasoning questions

Connect logic to programming (IF statements)
