Definitions Bank

A. Checking if current_hour > 12 to switch a clock from AM to PM mode.

B. A single letter, digit, or symbol key on a keyboard.

C. An extension that allows a program to read time out loud to help visually impaired users.

D. An arithmetic operator that finds the remainder after dividing two integers.

E. Following a recipe step-by-step: getting a bowl, pouring cereal, adding milk.

V. Arrange in Proper Sequence

Number the steps in the correct logical order (1, 2, 3, etc.).

Task 1: Execution of a Cereal-Making Algorithm

Pour in some cereal into the bowl

Get a bowl from the cupboard

Eat your breakfast

Add milk to the bowl

Task 2: Program Sequence for a Chatbot Greeting & Age Processing

Compute born_year = current_year - answer using an arithmetic operator.

Display: "Hello, my name is James".

Prompt user: "How old are you?" and wait for response.

Output message joining text and calculated year.

VI. True or False

State whether each statement is True or False. If False, provide a 1-sentence correction.

1. In Scratch programming, the forward slash (/) is used as the arithmetic operator for division.

True False

2. A forever loop in Scratch repeats a set of code a fixed number of times (such as 10 times) and then stops.

True False

3. An integer variable can store numbers with fractional decimal points, such as 3.14 or 0.5.

True False

4. A string data type is used for text messages and can contain letters, numbers, and spaces.

True False

5. Comparison operators, such as greater than (>), evaluate an expression and output either True or False.

True False

6. Chatbots on the Internet are completely secure, so it is fine to share personal private data with them.

True False

VII. Short Recall

1. List any three basic programming constructs used to control code execution.

2. List any two comparison (relational) operators used in algorithms.
