Lesson 8. Variables and Data Tracking

• Brief recap of conditional farming algorithms and a starter logic quiz

• Introduction to variables as named storage locations for data in memory

• Demonstrating variable creation in MakeCode for tracking numbers and items

• Teacher modelling: creating a counter variable to track blocks mined by Agent

• Guided task: initializing, updating, and outputting variable values on screen

• Student activity: code the Agent to count specific resource types encountered

• Discussion on data types: integers, strings, and booleans in computer science

• Interactive check: tracking variable state changes through a code trace table

• Independent task: create a resource collection scoreboard using variables

• Debugging exercise: fixing scope and initialization errors in variable logic

• Student reflection on how variables allow dynamic program outputs

• Lesson wrap-up summarizing variable declaration, assignment, and modification
