Mastering Selection in Flowcharts

Mastering Selection in Flowcharts

Learning Objective

At the end of the lesson, you will be able to create flowcharts with selection and understand the keywords associated with it.

What do you already know about flowcharts and selection?

What are Flowcharts?

Flowcharts are visual representations of a process or algorithm, using different symbols to represent various actions and decisions.

Selection in Flowcharts

Selection is a decision-making process in flowcharts where certain actions are taken based on specific conditions or criteria.

Selection Symbols

Selection symbols include the diamond shape, which represents a decision point, and arrows to indicate different paths based on conditions.

Example Flowchart: Odd or Even

Here's an example flowchart that determines if a number is odd or even using selection.

Frayer Model: Decision

Use a Frayer model to define and illustrate the keyword 'Decision' in the context of flowcharts and selection.

Example Flowchart: Grade Classification

Let's explore another example flowchart that classifies grades based on a student's score.

Frayer Model: Condition

Use a Frayer model to define and illustrate the keyword 'Condition' in the context of flowcharts and selection.

Common Keywords in Selection

Some common keywords used in selection include 'if', 'else', 'else if', 'switch', and 'case'.

Example Flowchart: Voting Eligibility

Let's explore one more example flowchart that determines if a person is eligible to vote based on age.

Frayer Model: Criteria

Use a Frayer model to define and illustrate the keyword 'Criteria' in the context of flowcharts and selection.

Practice Activity

Now it's time for you to create your own flowchart with selection. Choose a simple scenario and use the appropriate symbols and keywords.

Frayer Model: Flowchart

Use a Frayer model to define and illustrate the keyword 'Flowchart' in the context of selection and its components.

Questions and Discussion

Open the floor for any questions or further discussion on flowcharts and selection.

Write down 3 things you learned in this lesson.

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.

Write down 2 things you want to know more about.

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
