Lesson Overview

Learners will explore sequencing as the order of instructions in coding. Through a short, hands-on activity, they will identify, arrange, and test steps to complete a simple task accurately.

Learning Objectives

Define sequencing as the order of instructions in a program.
Arrange simple instructions in the correct sequence.
Explain why order matters in coding and problem-solving.
Test a sequence and identify errors caused by incorrect order.

Materials Needed

Whiteboard or projector
Markers or slides
Printed or displayed step cards for a simple task (e.g., making a sandwich or logging into a website)
Pens and paper, or sticky notes
Optional: simple coding blocks or pseudocode example

Vocabulary

Term	Definition
Sequencing	The order in which instructions are carried out.
Algorithm	A set of step-by-step instructions to complete a task.
Debug	To find and fix mistakes in a program.
Instruction	A direction that tells the computer or person what to do next.

Lesson Sequence

Warm-Up: Everyday Sequencing3 minutes

Teacher Actions

Ask learners: 'What happens if we do steps in the wrong order, like making coffee before adding water?' Elicit a few quick examples and connect answers to coding.

Student Actions

Share everyday examples of step order and briefly discuss why order matters.

Direct Instruction: What Is Sequencing?4 minutes

Teacher Actions

Define sequencing and algorithm. Show 4–5 simple steps for a familiar task on the board. Model how changing the order affects the result.

Student Actions

Listen, take notes, and answer quick oral questions about which step should come first, next, and last.

Guided Practice: Arrange the Steps5 minutes

Teacher Actions

Give learners a set of mixed-up step cards for a simple process. In pairs, have them arrange the steps in the correct order and justify their choices.

Student Actions

Work with a partner to sequence the cards, discuss reasoning, and make changes if needed.

Apply and Share: Test the Sequence2 minutes

Teacher Actions

Invite one or two pairs to share their sequence. Ask the class to check whether the order makes sense and identify any errors.

Student Actions

Present answers, compare sequences, and suggest corrections when necessary.

Closure: Exit Reflection1 minute

Teacher Actions

Summarize: sequencing means giving instructions in the correct order. Ask learners to name one reason sequencing is important in coding.

Student Actions

Respond with one sentence or one example showing understanding.

Support

Use familiar, non-technical examples before moving to coding language.
Provide partially completed sequences for learners who need extra support.
Pair stronger and developing learners for the card-sort activity.
Use visuals or color coding to show first, next, and last steps.

Challenge

Ask advanced learners to write their own 4-step algorithm for a simple daily task.
Challenge learners to predict what would happen if one step in the sequence were removed or moved.
Have learners convert their sequence into simple pseudocode or coding blocks.

Checks for Understanding

Ask: 'Which step must come first? Why?'
Ask: 'What happens if two steps are switched?'
Listen for correct use of sequencing vocabulary during pair discussion.
Observe whether learners can reorder steps accurately without teacher prompting.

Closure

Reinforce that sequencing is essential because computers follow instructions exactly as written. Remind learners that correct order helps programs work as intended.
