Teach selection with a complete lesson that’s ready to go.

Selection is where programs start making decisions, and it appears in almost every exam programming question. This pack takes students from “what is a condition?” to writing and tracing if, elif and else structures with confidence. It is aligned to Cambridge IGCSE Computer Science 0478 / 9618 (Programming) and needs no prep.

WHAT’S INCLUDED

• PowerPoint lesson ([X] slides): worked examples, live-code demos and built-in check-for-understanding questions

• Student worksheet ([X] pages): scaffolded tasks from recall, to predicting outputs, to exam-style problems

• Hands-on coding activity: students write programs that make decisions, such as a grade calculator or a login check

• MCQ quiz ([X] questions): quick-fire questions to check understanding and catch misconceptions

• Answers and full mark scheme: model answers with mark allocations, so marking takes minutes

WHAT STUDENTS WILL LEARN

What selection is and why programs need it
Conditions built with comparison operators: == != < > <= >=
if, elif and else structures, and how Python decides which branch runs
Combining conditions with and, or and not
Nested selection: an if inside another if
Indentation and colons: the syntax rules Python enforces
Tracing selection code to predict the output
Choosing between several separate if statements and one if-elif chain
How each Python structure maps to the IF and CASE structures in Cambridge pseudocode
Common errors: = vs ==, missing colons, wrong indentation, conditions in the wrong order, and x == 1 or 2

WHY TEACHERS LOVE IT

Exam-focused: questions follow Cambridge command words and mark-scheme style
Targets real misconceptions: the mistakes students make every year
Differentiated: support tasks plus stretch questions for top-grade students
Non-specialist friendly: clear explanations and full answers included
Flexible: works as a single lesson, homework, cover or revision
Print-and-go: no editing needed (editable PPT included)

PERFECT FOR
Cambridge IGCSE 0478 teachers, heads of department, non-specialist and cover staff, and students learning independently. It suits ages 14-16 (Year 10-11 / Grade 9-10).
