Parts of a ComputerActivities & Teaching Strategies
Active learning helps Year 1 students grasp abstract computer parts by connecting them to tangible actions. When children physically interact with devices, they build lasting mental models of how computers function and why each part matters.
Learning Objectives
- 1Identify the main external parts of a computer and describe their functions.
- 2Explain how the keyboard and mouse act as communication tools between a user and a computer.
- 3Compare the physical appearance and primary use of at least two different digital devices.
- 4Predict the impact of removing a key component, like the screen or keyboard, on a computer's functionality.

Stations Rotation: Computer Parts Hunt
Prepare four stations with real or model computers: one for input devices (keyboard, mouse), one for output (screen), one for internals (pictures or safe models), and one for comparing devices. Students rotate every 7 minutes, labeling parts on worksheets and noting functions. Conclude with a share-out.
Prepare & details
Analyze what happens to a computer if one of its parts is missing.
Facilitation Tip: During the Computer Parts Hunt, place a disassembled keyboard under one sheet to encourage careful observation and questioning.
Setup: Tables/desks arranged in 4-6 distinct stations around room
Materials: Station instruction cards, Different materials per station, Rotation timer
Pairs: Build-Your-Computer
Provide cut-out paper parts for screen, keyboard, mouse, CPU, and storage. Pairs match and glue them onto a computer outline, then write or draw what happens if one is missing. Pairs present one prediction to the class.
Prepare & details
Explain how the mouse and keyboard help us talk to the computer.
Facilitation Tip: In Build-Your-Computer, circulate with a checklist to ensure pairs name each part and its function aloud before gluing.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Whole Class: Missing Parts Demo
Use a toy computer or projector to remove parts one by one, like covering the screen or unplugging the mouse. Class discusses and records effects, such as no images or no cursor movement. Vote on most critical part.
Prepare & details
Justify why different digital devices look so different from each other.
Facilitation Tip: For the Missing Parts Demo, intentionally leave one device part off each station so students quickly notice the impact on use.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Individual: Device Comparison Sketch
Students draw two devices they use, like a phone and laptop, labeling three parts each and noting one design difference. Collect sketches for a class display wall.
Prepare & details
Analyze what happens to a computer if one of its parts is missing.
Facilitation Tip: During Device Comparison Sketch, provide magnifying glasses for screen texture exploration to spark observations about portability and function.
Setup: Wall space or tables arranged around room perimeter
Materials: Large paper/poster boards, Markers, Sticky notes for feedback
Teaching This Topic
Teachers know that Year 1 students learn best when they connect new information to their bodies and senses. For computer parts, hands-on stations and role-play help students move from guesses like 'the screen is the brain' to accurate understandings. Avoid long explanations—instead, let students test ideas with real devices and discuss findings in small groups.
What to Expect
By the end of these activities, students will confidently name and describe the roles of common computer parts, explain why missing parts cause problems, and compare how different devices meet different needs. Success looks like clear explanations, accurate labeling, and thoughtful comparisons.
These activities are a starting point. A full mission is the experience.
- Complete facilitation script with teacher dialogue
- Printable student materials, ready for class
- Differentiation strategies for every learner
Watch Out for These Misconceptions
Common MisconceptionDuring Station Rotation: Computer Parts Hunt, watch for students who point to the screen and call it the brain.
What to Teach Instead
Bring the disassembled keyboard to the group and ask students to trace the path from their finger on a key to the screen lighting up, naming each part along the way.
Common MisconceptionDuring Pairs: Build-Your-Computer, watch for students who arrange parts randomly, assuming all devices work the same.
What to Teach Instead
Prompt pairs to discuss why a tablet’s parts are smaller than a desktop’s, then adjust their build to reflect a specific use like portability or large screen.
Common MisconceptionDuring Whole Class: Missing Parts Demo, watch for students who think the computer still works without a mouse.
What to Teach Instead
Have students act out typing a sentence without a keyboard to show how input devices send instructions, then repeat the task with and without the mouse to see the difference.
Assessment Ideas
After Station Rotation: Computer Parts Hunt, hold up a picture of a screen, keyboard, and mouse. Ask students to point to each part and say its name and one function aloud.
After Build-Your-Computer, give each student a labeled drawing of a simple computer. Ask them to draw and label the screen, keyboard, and mouse, then write one sentence about what would happen if the keyboard were missing.
During Device Comparison Sketch, hold up a tablet and a desktop computer. Ask students to name parts the devices share, then discuss why one has a larger screen or no mouse, recording their ideas on chart paper.
Extensions & Scaffolding
- Challenge: Provide a broken or old device for students to sketch, labeling parts and writing or drawing what might be wrong with it.
- Scaffolding: Offer tactile 3D labels with braille or raised letters for students who need extra sensory input during the Build-Your-Computer activity.
- Deeper exploration: Ask students to research why a computer might have a touchscreen but no mouse, then present their findings to the class.
Key Vocabulary
| Screen | The part of a computer that shows images, text, and videos. It is where you see what the computer is doing. |
| Keyboard | A set of buttons with letters, numbers, and symbols used to type information into the computer. |
| Mouse | A small device that you move with your hand to control a pointer on the screen and select items. |
| Internal Components | Parts inside the computer's case, such as the processor and storage, that help it to work and remember information. |
