JHS2 Computing · Term 3 Week 8: Introduction to Programming

Lesson notes

Indicator: B8.4.1.1.1

By the end of the lesson, learners can:

Define constants, variables, expressions, and statements or instructions in their own words with at least one example of each.
Distinguish between logical operators (AND, OR, NOT) and arithmetic operators (+, -, ×, ÷, %) and apply them correctly in simple expressions.
Evaluate simple programming expressions by applying the correct order of operator precedence (e.g., 3 + 4 × 2 = 11, not 14).
Convert a simple arithmetic expression written in classroom mathematics into a programming expression using symbols like * and /.
Complete a comparison table showing how the same arithmetic notation is represented in coding versus classroom mathematics.
