Code Crew: Grade 4
Building the ship.
The bridge from "I can read a small program" to "I can write one of my own." Lists of records, structured I/O, early string methods.
10 to 15 minutes a day, four or five days a week.
What kids will learn
Code Crew: Grade 4 is the Crew Engineer chapter of the Code Crew ladder. The bridge from blocks to text. Real algorithms, structured data, functions, and small programs your kid designs and ships.
- Work with lists of records and small dictionaries
- Read input, process it, and print structured output
- Use early string methods (split, join, slice)
- Trace a program by hand to predict its output
- Refactor a 30 line program into smaller functions
- Choose between a list and a dictionary for the right job
Sample activities
Two short looks at what a session inside Code Crew: Grade 4 actually feels like.
Launch scheduler
Given a list of launch windows, pick the next one that has not passed and is not cloudy. Kids see for the first time how a real program looks at a list of records, filters it, and returns the best match.
Fuel budget
Three engines, three fuel types, one budget. Kids write a small program that adds up the costs, prints a table, and decides if the mission can fly. It is a spreadsheet, but with code.
Is it the right fit?
Built for Grade 4 students (ages 9 to 11) who have either finished Grade 3 or are comfortable with sequencing, loops, conditionals, and a little bit of typing.
