Make operators and expressions click, with a complete lesson that’s ready to teach.

Operators are where students start turning Python into real problem-solving, and where marks are won or lost in the exam. This pack takes students from basic arithmetic to confidently building, tracing and evaluating expressions. 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 and run programs that use operators to solve practical problems

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

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

WHAT STUDENTS WILL LEARN

Arithmetic operators: + - * / and exponent **
Integer division and modulus: // and %, linked to the DIV and MOD used in Cambridge pseudocode
Comparison operators: == != < > <= >=
Logical operators: and, or, not
Operator precedence: the order Python evaluates an expression, and when to use brackets
Building expressions that combine variables, values and operators
Assignment shortcuts such as += and -=
String concatenation with +
Common errors: = vs ==, integer vs real results, and precedence mistakes

WHY TEACHERS LOVE IT

Exam-focused: questions follow Cambridge command words and mark-scheme style
Targets real misconceptions: the errors 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).
