Lesson Overview

Students will learn how to identify an author’s purpose and apply that idea to code by examining whether a program is meant to inform, persuade, or entertain. Using simple examples and short discussion, students will connect purpose to design choices in coding.

Learning Objectives

Define author’s purpose in a coding context.
Identify whether a piece of code is intended to inform, persuade, or entertain.
Explain how code structure and comments can reveal purpose.
Apply author’s purpose to a short code example or pseudocode.

Materials Needed

Projector or board
Printed or displayed short code snippets/pseudocode
Pens or laptops
Exit discussion prompt or quick response form

Vocabulary

Term	Definition
Author’s Purpose	The reason an author creates a text or code; in coding, the intended goal of the program or script.
Inform	To provide information, explain, or teach.
Persuade	To convince the user to think, feel, or act in a certain way.
Entertain	To amuse, engage, or create an enjoyable experience.
Comment	A note in code that explains what the code does and can help reveal purpose.

Lesson Sequence

Warm-Up5 minutes

Teacher Actions

Display a short webpage message, app prompt, or simple code snippet and ask: What is this trying to do?

Student Actions

Share quick ideas and guess the purpose of the example.

Mini-Lesson8 minutes

Teacher Actions

Explain author’s purpose and connect it to coding by showing examples of code that informs, persuades, or entertains. Highlight clues such as function names, comments, user prompts, and output.

Student Actions

Listen, take notes, and answer brief questions about each example.

Guided Practice7 minutes

Teacher Actions

Present 2-3 short code snippets or pseudocode examples. Model how to identify purpose using evidence from the code.

Student Actions

Work with the teacher to classify each example and justify their choice with one clue from the code.

Independent Practice7 minutes

Teacher Actions

Give students one short code example and ask them to label its purpose and write one sentence explaining why.

Student Actions

Independently identify the purpose and support their answer with evidence from the code.

Share Out3 minutes

Teacher Actions

Invite a few students to share answers and clarify any misunderstandings.

Student Actions

Share responses and compare reasoning with classmates.

Support

Provide sentence frames such as: 'This code’s purpose is ___ because ___. '
Use very short snippets with clear clues and simple language.
Allow partner discussion before individual responses.
Offer a word bank with inform, persuade, entertain, comment, output, input.

Challenge

Ask students to identify multiple possible purposes if a snippet combines goals.
Have students revise a snippet’s comments or output to make its purpose clearer.
Invite students to explain how purpose affects design choices such as tone, labels, or prompts.

Checks for Understanding

Ask students to point to one specific clue that reveals purpose.
Use thumbs up/down after each example to check understanding.
Collect one-sentence written responses from independent practice.
Listen for accurate use of vocabulary during discussion.

Closure

Review the three purposes and ask students to name one code clue that can help identify purpose. End with a quick recap: good code communicates its goal clearly to the user and the programmer.
