Student lesson
- Simple machines make work easier.
- Ramps, wheels, levers and wedges are simple machines.
- Pulleys lift loads.
- Tools often combine machines.
Words to know
a tool that makes work easier
a pointed piece that splits or cuts
a wheel with a rope that lifts loads
something used to do a job
1. Discover: The toolshed
Mr Quaye opens the school toolshed. He shows a spade, an axe, a wheelbarrow and a rope-and-wheel for the well. “Each is a simple machine or uses one,” he says. “They help us to work.”
Think: Which tool is a lever?
2. Understand: Simple machines
Idea 1: Types
The main simple machines are the ramp, the lever, the wheel and axle, the wedge and the pulley.
Idea 2: What they do
Ramps lift loads. Levers pry and lift. Wheels roll loads. Wedges cut and split. Pulleys lift with ropes.
Idea 3: Combined
A wheelbarrow combines a wheel and axle and a lever. A bicycle uses wheels, levers and pulleys (the chain). Many tools use more than one.
3. Worked examples
Example 1 (I show you): Name it
An axe.
- Pointed blade.
- Splits wood.
- Wedge.
Answer: An axe is a wedge.
Example 2 (We do it together): Combined
Wheelbarrow.
- Wheel and axle.
- Lever handles.
- Two machines.
Answer: A wheelbarrow combines two machines.
Example 3 (You try): Pulley
A well rope.
Show the steps and answer
- Wheel guides rope.
- Lifts load.
- Pulley.
Answer: A pulley lifts loads.
Did you know?
A bicycle is a clever mix of levers, wheels and axles, and a chain-and-gear system.
Why this matters
Simple machines let people do heavy work with less effort.
4. Explore: Machine hunt
Find simple machines in the classroom or at home.
- List tools.
- Name the machine type.
- Draw three.
- Share with a partner.
Think about it: what did you notice?
What did you notice? Many tools are simple machines.

If a learner struggles
- Find the misconception: “Machines are only electric.” Many are simple.
- Explain another way: use real objects, pictures or actions first, then words.
- Show a simpler example: Name and explain five simple machines.
- Guided practice: work through one example together and let the learner try the next one.
- Reassess: use the quiz again or the worksheet.
- Move on when the learner shows Silver-level evidence independently.
For parents and guardians
In this lesson your child names simple machines in everyday tools. You do not need to be an expert to help.
- Look at tools together.
- Ask, “Which machine is it?”
- Draw one.
- Ask “how do you know?” after each answer, and listen.
- Praise effort, not only right answers. Mistakes are how we learn.
- Ten to fifteen minutes a day is better than one long session.
Teacher package
1–5. Objectives, prerequisites, materials, preparation, duration
Lesson objectives. Learners will: name simple machines; find them in tools; explain what each does; classify everyday tools.
Prerequisite knowledge. Grade 1 ideas: pushing and pulling, things that move and making things move faster or slower.
Materials. Tool pictures, paper and pencils. Low-resource options: use chalk or charcoal on a board or wall, drawings in the sand, and objects from the classroom instead of printed materials.
Preparation. Print tool pictures. Prepare sorting mats.
Suggested duration. 45–60 minutes. It can be split into two shorter sessions.
6–9. Teaching procedure, explanation notes, guided and independent activities
Introduction (5 min). Show a toolbox picture and ask, “Which tool is which machine?”
Explanation (10 min). Teach machines.
Guided activity (10 min). Learners sort tools.
Independent activity (10 min). Learners design.
Assessment and reflection (5 min). Ask each learner to say one thing they learned and how they know it.
Key questions. Which machine? How does it help?
Teacher explanation notes. Start with real objects and safe, hands-on observation. Then talk about what was seen, then draw and write. Always say “how do you know?”. Keep to the safety notes, and use local, safe materials.
10–12. Differentiation, formative assessment, common misconceptions
Support. Use real objects and pictures, short sentences and a partner. Let learners point, show or draw instead of writing. Extension. Ask learners to find a new example at home and explain how they know.
Formative assessment. Listen to learners read and explain, ask “how do you know?”, and check the independent work.
Misconceptions. “Machines are only electric.” Many are simple.
13–15. Assessment questions, answer keys, marking scheme
Use the quiz, the 9-mark exam practice and the worksheet on this page. All answers and marking guides are in the answer sections above. Re-check every answer before use.
16–19. Remediation, enrichment, homework, teacher reflection
Remediation. Name and explain five simple machines. Enrichment. Look for one new example near your home or school, draw it and explain it to someone. Homework. See above.
Teacher reflection. After teaching, record: which ideas learners understood; which misconceptions occurred; which activities worked; which learners need more practice; and what to improve next time.
