Lesson 4. Automated Construction with Count Loops

• Brief recap of relative coordinates and a starter quiz on spatial offsets

• Introduction to iteration and efficiency in visual code blocks

• Comparing manual block placement sequences against automated repeat loops

• Teacher modelling of constructing a repeat loop to lay down a line of blocks

• Guided practice: building a simple wall using count-controlled repeat loops

• Student task: design an algorithm for the Agent to build a square enclosure

• Debugging session: identifying off-by-one errors in loop execution counts

• Discussion on computational efficiency and reducing code duplication

• Check for understanding: matching loop structures to their visual outputs

• Independent practice: modifying code to build walls of varying dimensions

• Peer review of block counts and loop efficiency in student programs

• Summary of count-controlled loops and introduction to nested repetition preview
