Loops inside loops
Put a loop inside a loop to draw rows, grids and woven patterns.
Planned. This module is part of the plan and is not written yet.
Why it matters
Planting a farm in rows means repeating 'plant a seed' along a row, then repeating whole rows. That is a loop inside a loop.

Inside the module.
4 lessons in order, about 45 minutes in all, then a short test. Learners go at their own pace; the minutes are a guide, not a timetable.
Draft outline · in review
Lesson 1: A loop inside a loop
See how the inner loop runs all the way through each time the outer loop runs once.
Explain10 min, from minute 0
Lesson 2: Rows of seeds
Plant a field of seeds, row by row, with two loops.
Worked example10 min, from minute 10
Lesson 3: Grids and woven patterns
Draw grids and basket-weave patterns with nested loops.
Practice15 min, from minute 20
Lesson 4: Count the runs
Work out how many times the inner block runs before running the program.
Practice10 min, from minute 35
End-of-module test
Build rows and grids with nested loops and work out how many times the inner instruction runs.
Mastered at 85% or more. Retake it until you pass; nothing is lost, and each try gives feedback.
Already know it? A Challenge Test (planned) clears the whole module: 90% overall, no objective below 75%.

Practicalities

Planned to run on the Lantern's own computer, with no internet needed.
Languages
Planned first in English; every module aims to reach all of the Lantern's languages.
Try a question.
One question from the module, as a learner would meet it. Have a go, then open the worked solution a step at a time.
Draft outline · in review
repeat 3 times [ repeat 5 times [plant a seed], move to the next row ]. How many seeds are planted?

What a learner can do after it
- Use a loop inside another loop to draw rows and grids.
- Work out how many times the inner instruction runs.

Alignments
None drafted yet.
Alignment in review until a qualified teacher or lecturer checks it. No exam body, university or vendor endorses us; learners still sit the real exam.
Challenge Test
Planned: a Challenge Test to prove you know it and skip it. Pass at 90% overall, with no objective below 75%.
The route here.
Everything this module builds on, drawn as a route from its foundations. Solid lanes must be mastered first, or cleared by a Challenge Test; dashed lanes are suggestions that never lock anything.
