Quick Questions
Shade in the A or B circle for each question.
1. Which text belongs in a process box that adds 1 to a counter?
2. Which text is correct inside a decision diamond?
3. Which text is correct inside a parallelogram to read a value from the user?
4. Which process box shows the correct way to store a value in a variable?
5. Which text is correct in a parallelogram to display a result?
B
Match the Pairs
Draw a line connecting each item on the left to its match on the right.
| Left column | Right column | |
|---|---|---|
| 1Total ← Total + Mark | AA process box that adds Mark to Total and stores the result back in Total | |
| 2Mark >= 50 | BA vague question is used instead of a precise condition. It should be Mark >= 50. | |
| 3A parallelogram that reads a value from the user into a variable uses the INPUT keyword | CA decision diamond condition that asks if Mark is 50 or more, with Yes and No exits | |
| 4A parallelogram that shows a result to the user uses the OUTPUT keyword | DA sentence is used instead of a pseudocode statement. It should be Count ← Count + 1. | |
| 5Process box: Add 1 to the counter | EINPUT Mark | |
| 6Decision diamond: Is the mark high enough to pass? | FOUTPUT Total |

Answer Key
Writing statements inside flowchart symbols
Section A: Quick Questions
Q1
B — Count ← Count + 1
Q2
A — Mark >= 50
Q3
A — INPUT Mark
Q4
B — Total ← 0
Q5
A — OUTPUT Total
Section B: Match the Pairs
Q1
Total ← Total + Mark → A process box that adds Mark to Total and stores the result back in Total
Q2
Mark >= 50 → A decision diamond condition that asks if Mark is 50 or more, with Yes and No exits
Q3
A parallelogram that reads a value from the user into a variable uses the INPUT keyword → INPUT Mark
Q4
A parallelogram that shows a result to the user uses the OUTPUT keyword → OUTPUT Total
Q5
Process box: Add 1 to the counter → A sentence is used instead of a pseudocode statement. It should be Count ← Count + 1.
Q6
Decision diamond: Is the mark high enough to pass? → A vague question is used instead of a precise condition. It should be Mark >= 50.
Section C: Definitions
Q1
Count ← Count + 1 — Flowchart symbols hold precise pseudocode, not sentences. Process boxes use ← statements like this, decisions use conditions like Mark >= 50, parallelograms use INPUT or OUTPUT.Section D: Fill in the Blanks
Q1
Count ← Count + 1Q2
Mark >= 50Q3
INPUT MarkQ4
OUTPUT TotalQ5
Total ← Total + MarkSection E: Spot the Error
Q1
B — Flowchart symbols must hold precise pseudocode, not sentences. The process box should say Total ← Total + Mark.
Q2
A — A process box sets a value with the assignment arrow ←, not =. It should be Count ← 0.
Q3
A — A parallelogram for input uses the INPUT keyword with the variable name, not a sentence. It should be INPUT Age.
Q4
C — Pseudocode uses the keyword OUTPUT for output, and PRINT is not a pseudocode keyword. It should be OUTPUT "Pass".
Q5
D — The arrow ← points from the value to the variable being set. The variable goes on the left, so it should be Total ← Total + Score.
