Practice - 5 Tasks

1fill in blank

easy

Complete the pseudocode to start planning by defining the first step.

Intro to Computing

START
DEFINE [1] AS the first step
END

Cfunction

Dloop

💡 Hint

Common Mistakes

Using programming terms like variable or function instead of a planning step.

Skipping the definition of the goal.

The first step in pseudocode planning is to define the goal clearly.

2fill in blank

medium

Complete the pseudocode to represent a decision point in planning.

Intro to Computing

IF condition [1]
  TAKE action
ELSE
  TAKE alternative action
END IF

Drag options to blanks, or click blank then click option'

Aloop

Bstart

CTHEN

DELSE

💡 Hint

Common Mistakes

Using ELSE instead of THEN after the condition.

Omitting the keyword after the condition.

In pseudocode, the keyword THEN follows the condition in an IF statement to indicate the action to take if the condition is true.

3fill in blank

hard

Fix the error in the pseudocode to correctly represent a loop for repeated actions.

Intro to Computing

FOR i FROM 1 TO 5 [1]
  PRINT i
END FOR

Drag options to blanks, or click blank then click option'

AWHILE

BDO

CREPEAT

DLOOP

💡 Hint

Common Mistakes

Using LOOP or REPEAT without DO.

Using WHILE incorrectly in a FOR loop.

The correct keyword to start the loop block in pseudocode is DO, indicating the actions to repeat.

4fill in blank

hard

Fill both blanks to complete the pseudocode for checking a condition and taking action.

Intro to Computing

IF [1] THEN
  [2] action
END IF

Drag options to blanks, or click blank then click option'

Acondition

Bperform

Crepeat

Dstart

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'repeat' instead of 'perform' for the action.

Using 'start' instead of 'condition' for the check.

The pseudocode checks a condition and then performs an action if true.

5fill in blank

hard

Fill all three blanks to create a pseudocode dictionary comprehension for planning steps with a condition.

Intro to Computing

steps = { [1]: [2] for [3] in plan if [2] != None }

Drag options to blanks, or click blank then click option'

Astep_name

Baction

Cstep

Dcondition

Attempts:

3 left

💡 Hint

Common Mistakes

Mixing up keys and values in the dictionary.

Using 'condition' as the loop variable.

This pseudocode creates a dictionary where each step_name maps to an action for each step in the plan, filtering out steps with no action.
