About this course
Code Crew Grade 2 introduces memory boxes (variables), counted loops, checks (if, then, otherwise) and named jobs (functions). Kids read every program line and answer by tapping, with zero typing required. The mystery: the fleet's auto-pilot makes every test ship drop at the same spot. Over 12 weeks kids collect clues, learn a real bug-hunt method, find the one wrong word, and ship the fix.
Kids will
- Use a memory box (variable) to store and change a number
- Use a counted loop, including one counted by a box
- Compare a box with a number and choose a path (if, then, otherwise)
- Name a job (function) and run it again with do
- Read an 8 to 10 line program and predict what it will do
- Find a bug step by step with a logbook

Inside the course
From Week 4
Kids trace a loop line by line and keep a logbook of the steps box. Lap after lap the ship holds steady, then drops on lap 5. The clue: the drop always comes when steps reaches 5.
From Week 7
Name a job called takeoff once, then run it with a single do takeoff line wherever it is needed. Kids count the lines it saves and feel the "name it once, reuse it" moment.
