When you write about an invention idea, include 3 parts

Name it: What is your invention called?
Tell what it does: What happens when someone uses it?
Tell how it helps: Why is it useful?

Example

Name: The Homework Helper Robot
What it does: It holds pencils and reads directions aloud.
How it helps: It helps kids stay organized and focused.
