Quick Questions
Shade in the A or B circle for each question.
1. In Scratch you make a custom block in My Blocks. Which Python keyword does the 'define' hat block turn into?
2. Which line runs (uses) a function called jump, like dragging the jump block into a script?
3. You define a Scratch My Block once and use it many times. What is the Python version of this?
4. Which function definition is written correctly in Python?
5. A My Block has an input called steps, like 'move (steps)'. How is this input written in Python?
B
Match the Pairs
Draw a line connecting each item on the left to its match on the right.
| Left column | Right column | |
|---|---|---|
| 1def cheer(): | AThe call is missing brackets, so the function is named but never run. | |
| 2cheer() | Bgreet() greet() greet() | |
| 3A My Block with an input, like 'jump (height)', becomes a function with a parameter | CThis is missing the def keyword, so Python cannot define the function. It also has no colon, so it is a call, not a definition. | |
| 4Reuse: define once, then use the My Block many times instead of copying blocks | DDefines a new function called cheer, like making a Scratch My Block with the define hat | |
| 5cheer() print('Go team!') | Edef jump(height): | |
| 6def cheer(): print('Go team!') cheer | FCalls the function so its code runs, like dragging the My Block into a script |

Answer Key
Scratch My Blocks as Python functions
Section A: Quick Questions
Q1
A — def
Q2
B — jump()
Q3
B — Define the function once, then call it many times
Q4
A — def dance():
Q5
A — def move_forward(steps):
Section B: Match the Pairs
Q1
def cheer(): → Defines a new function called cheer, like making a Scratch My Block with the define hat
Q2
cheer() → Calls the function so its code runs, like dragging the My Block into a script
Q3
A My Block with an input, like 'jump (height)', becomes a function with a parameter → def jump(height):
Q4
Reuse: define once, then use the My Block many times instead of copying blocks → greet()
greet()
greet()
Q5
cheer()
print('Go team!') → This is missing the def keyword, so Python cannot define the function. It also has no colon, so it is a call, not a definition.
Q6
def cheer():
print('Go team!')
cheer → The call is missing brackets, so the function is named but never run.
Section C: Definitions
Q1
def — Makes a Python function, like defining a Scratch My Block once. Run it any time by calling its name, e.g. greet(). Inputs become parameters, so you reuse the code instead of copying blocks.Section D: Fill in the Blanks
Q1
def cheer():
print("Go team!")Q2
def cheer():
print("Go team!")
cheer()Q3
def cheer():
print("Go team!")
cheer()Q4
def hello(name):
print("Hi", name)
hello("Zoe")Q5
def bonus(points):
print(points + 10)
bonus(5)Section E: Spot the Error
Q1
C — Writing only the name does not run the function. Like dragging out a My Block, you must call it with brackets: jump().
Q2
C — The call is missing its closing bracket. The block input 3 must go inside a full pair of brackets: spin(3).
Q3
B — The print call inside the function is missing its closing bracket. It should be print("Clap!").
Q4
A — The def line must end with a colon. It should be def move(steps):.
Q5
A — Python uses the keyword def, not function, to define a function (like the define block in Scratch). It should be def say_hi(name):.
