Boolean Logic & Logic Gates| PPT| Worksheet| Activity| MCQ Quiz|Answers|Cambridge IGCSE 0478 / 0984

Logic gates made visual, intuitive, and exam-ready. Covers AND, OR, NOT, NAND, NOR and XOR gates with correct 0478 symbols, truth table construction for combined circuits, and converting between circuit diagrams and logic expressions. Includes an animated PPT, 8 circuit-to-truth-table conversion exercises, 6 problem-to-circuit design tasks, a 15-question MCQ quiz, and fully worked truth tables and diagrams in the answer key. One of our best-rated topics — students consistently say this is where logic “finally makes sense.”

1. PPT (28 slides) — Cover, learning objectives, intro to gates, then AND/OR/NOT/NAND/NOR/XOR each with drawn 0478-style symbol, truth table, and real-world analogy, a full gate summary table, combining-gates methodology, three fully worked combined-circuit examples (2-gate, 3-gate with NOT, full 8-row 3-input table), circuit↔expression conversion both directions, common exam question types, exam tips, a quick-reference card, real-world computing links, practice slides, recap, and next-steps slide.

2. Worksheet — Section A: 8 circuit descriptions (single gates up to 3-input, 2-3 gate combinations) with blank truth-table grids to fill in. Section B: 6 problem statements (door/engine, alarm, sprinkler, car start, vending machine, greenhouse fan) requiring expression + circuit description. Section C: 5 expression↔truth-table conversion questions.

3. Activity — “Human Logic Gates” kinaesthetic activity with full teacher running order (30 min), materials list, and 6 printable gate cards (AND/OR/NOT/NAND/NOR/XOR) with differentiation and extension tasks for 3-input circuits.

4. MCQ Quiz — 15 questions (5 easy/5 medium/5 hard), mixing truth-table-output questions and gate-identification questions.

5. Answers/Marking Scheme — Every truth table fully worked and double-checked computationally (I verified all values in Python before finalizing, and caught/corrected one error in my own draft MCQ key for Q15), full circuit descriptions and expressions for all 6 word problems, complete Section C answers, and an MCQ answer key with one-line justifications plus suggested grade boundaries.

All worksheets are print-ready.

Fully editable resources.

Great for: classroom teaching, revision lessons, flipped learning, homework tasks.
