Open Ended

How do the concepts of 'street' and 'avenue' help in navigating Karel's World?

Multiple Choice

What is the purpose of the walls in Karel's World as shown in the images?

• To mark boundaries and obstacles for Karel

• To show where Karel can collect beepers

• To indicate Karel's starting position

• To display the direction Karel is facing

Multiple Choice

What happens when the put_ball() command is executed by Karel?

• Karel moves forward one space.

• Karel turns to the left.

• Karel places a ball on its current spot.

• Karel picks up a ball from its current spot.

Multiple Choice

Which command should Karel use to pick up a ball from its current location?

• move()

• turn_left()

• put_ball()

• take_ball()

Open Ended

Describe a possible sequence of moves and actions Karel could take to go from the starting world to the ending world in the last image.

Multiple Select

Which of the following are rules for writing Karel commands?

• No spaces in commands

• Commands must match exact capitalization

• Commands can have numbers

• Every command ends in ()

Multiple Choice

How can Karel simulate turning right if the turn_right() command is not available?

• By turning left three times

• By moving forward and turning left

• By turning left once

• By turning around

Multiple Choice

Why can't Karel use the command turn_right()?

• Because Karel's programming does not include turn_right()

• Because turn_right() is a dangerous command

• Because Karel can only move forward

• Because Karel can only turn left

Open Ended

Describe the sequence of commands Karel would need to use to go from the starting world to the ending world as shown.

Multiple Choice

What is the main purpose of using functions when programming Karel?

• To teach Karel new commands and simplify code

• To make Karel move faster

• To change Karel's appearance

• To increase the number of beepers Karel can carry

Multiple Select

Which of the following are other names for a function as described in the lesson?

• Procedure

• Task

• Process

• Loop

Open Ended

Explain why teaching Karel new commands, like turn_right(), might be useful when solving problems.

Multiple Choice

Which directions can Karel face in his world?

• North, South, East, West

• Up, Down, Left, Right

• Forward, Backward, Left, Right

• North, East, South, Up

Multiple Choice

When Karel is facing East and executes turn_left(), which direction will Karel face?

• North

• West

• South

• East

Multiple Choice

How can you make Karel turn right if there is no turn_right() command?

• Use turn_left() three times

• Use turn_left() two times

• Use turn_left() four times

• Use move() and turn_left()

Multiple Choice

Why can't Karel use the command turn_right()?

• Because Karel is only programmed to turn left

• Because turn_right() is not a valid command for Karel

• Because Karel can only move forward

• Because Karel can only turn around

Open Ended

Explain why it might be useful to define a new function for Karel to turn right, even though there is no built-in turn_right() command.

Multiple Choice

Why do we use functions in programming?

• Break down our program into smaller parts

• Avoid repeating code

• Make our program more readable

• All of the above

Multiple Choice

What is top down design?

• Top down design is a way of designing your program by starting with the biggest problem and breaking it down into smaller and smaller pieces that are easier to solve.

• Top down design is a way that you can create designs on a computer to put on a web page

• Top down design is a way of designing your programs starting with the individual commands first

• Top down design is a way to use loops and classes to decompose the problem

Multiple Choice

What is a code comment?

• A way to teach Karel a new word

• A way to give notes to the reader to explain what your code is doing

• A message to your teacher in code

• A place to write whatever you want in your code

Multiple Choice

Why are preconditions and postconditions important in comments?
