BIG IDEA
Understand the idea before memorising a rule.
Arrays is part of python. At Grade 7, the goal is to connect this topic to a clear method, relevant evidence and a final check. You will apply that idea to a real python question at this grade level.
YOU WILL LEARN TO
- Explain the key ideas in arrays using accurate coding vocabulary.
- Apply a reliable method to a new arrays task.
- Check the result and explain why the evidence supports it.
METHOD
A reliable three-step approach
- 1
Break the task into small inputs, actions and outputs.
- 2
Build and test one part at a time.
- 3
Read errors carefully, improve the code and test edge cases.
WORKED EXAMPLE
During a homework check for Grade 7, which Python keyword starts a conditional decision?
Model response
The correct answer is if. Python uses if to run code when a condition is true.
