Complete Python Programming Unit – 8 Structured PPT Lessons: Variables, Operators, Selection, Iterat

A complete, ready-to-teach 8-lesson Python programming unit for KS3/KS4 Computer Science, covering everything from variables and data types through to local and global functions. Every lesson follows the same tried-and-tested structure — retrieval starter, spec-referenced explanation, modelled examples (Python + pseudocode side by side), collaborative tasks, self/peer AFL quizzes with answers, tiered challenge and extension tasks, and a plenary — so students build routine and confidence lesson after lesson, and you spend zero time reformatting or rewriting slides. Fully editable, classroom-tested, and ideal for both specialist and non-specialist CS teachers.

The consistent slide structure (worth calling out explicitly in your listing)

1 Unit/Topic title Orients students to the lesson
2 Learning Objective (LO) Clear, consistent LO stated up front and repeated on every slide
3 “From the Spec” Direct link to exam specification content
4 Retrieval/starter (e.g. “Clips – Write Round”) Low-stakes recall of prior knowledge
5 Retrieval task Hands-on quick practice (e.g. live coding in an online compiler)
6 Critical thinking Code-reading/analysis task, deeper engagement
7–9 Explanation + worked examples Concept taught with Python + pseudocode comparisons
10 Collaboration task Pair/group application task
11–12 AFL quiz + answers Self/peer-assessed multiple choice for formative checking
13–14 Challenge + Extension tasks Tiered stretch for stronger students
15 Answers Model solutions for challenge/extension
16 Plenary Consolidation/exit task

This same 16-slide skeleton runs through all 8 topics, just with content swapped in — so in your listing you can honestly say "identical, easy-to-follow structure across the whole unit.
