Exit Ticket

Preview the three formative checks. Tap “Sample answer” to see what mastery looks like — hide them before you print for students.

QUESTION 1
What is the difference between a compiled and an interpreted language?
A compiled language is translated to machine code before running (fast); an interpreted one runs line by line as it executes.
QUESTION 2
Name one kind of programming language and what it is good for.
For example, scripting (Python) for quick websites and data, or compiled (C++) for fast games and systems.
QUESTION 3
Why are there so many programming languages?
Each is designed for different goals (speed, ease, safety, or a specific job), so no single language is best for everything.

Create: a language guide.

Have students pick four programming languages, note what each is good for, and make a one-page guide they can use when choosing a language for a project. A printable programming-languages worksheet is in the Computer Science library.
