Follow a repeated instruction
Trace a loop by keeping a clear record of changing values.
Open lesson 1Combine Loops and Function Inputs
Trace loop scope, nested repetitions, two accumulators and independent function calls.
Before you begin
- Add signed integers; trace a single loop; read simple comparisons and lists.
Choose by skill rather than age alone. Read with an adult when useful, revisit a lesson, or explore another grade.
Follow the lesson sequence
Trace a Repeat Inside a Repeat
Distinguish outer iterations, inner iterations and initialization scope.
Open lesson 2Keep a Count and a Sum
Use two accumulators to describe selected list values.
Open lesson 3Trace a Function Call Separately
Substitute parameters, follow a local loop and return its result.
Open lesson 4Review and transfer
After the lessons, try 4 new review cases and a practical task. Each answer has an explanation and a link back to the related lesson.
