Flowcharts Study Guide

1. Basic Symbols

Flowcharts use various symbols to represent different elements in a process:

• Start/End: Indicates the beginning or end of a process.
• Input/Output: Represents data input or output.
• Process: Denotes a specific action or operation.
• Decision: Represents a conditional or branching point in the process.
• Connector: Indicates a connection to another part of the flowchart.

2. Flowchart Construction

To create a flowchart, follow these basic steps:

1. Start with a start/end symbol to represent the beginning of the process.
2. Add process symbols to represent the individual steps or actions in the process.
3. Use decision symbols to show points where the process branches based on a condition.
4. Connect the symbols with arrows to indicate the flow of the process.
5. End with a start/end symbol to represent the completion of the process.

3. Reading and Understanding Flowcharts

When reading a flowchart, start at the start/end symbol and follow the arrows to understand the sequence of steps and decision points. Pay attention to the decision symbols to understand the conditions that determine the flow of the process.

4. Practice Problems

Try creating flowcharts for various processes, such as making a sandwich, solving a math problem, or completing a simple task. This practice will help reinforce your understanding of flowchart construction and interpretation.
