Lesson Plan for Primary Three (First Term)
Subject: Basic Science
Class: Primary Three
Week of the First Term: 1st Week
Topic: Measurement of Length
Sub-Topic: Meaning and Instrument of Measuring Length
Instructional Objectives
At the end of the lesson, pupils should be able to:
- Define length and identify it as a measurable attribute.
- Name at least three instruments used to measure length, such as a ruler, measuring tape, and meter stick.
- Demonstrate how to measure objects using a ruler with accuracy.
Entry Behaviour
Pupils should already know basic concepts of size and comparison (e.g., big vs. small, long vs. short).
Instructional Materials
- Textbook
- Rulers, measuring tapes, meter sticks
- Visual aids and charts

Content
- Meaning of Length
Length is the measurement of something from one end to the other.
- Instruments of Measuring Length
- Ruler: Used to measure shorter lengths, typically up to 30 centimeters or 12 inches
- Tape Measure: Useful for measuring longer lengths and curved surfaces. Commonly used in sewing, construction, and other fields
- Meter Stick: Used for measuring longer lengths than a standard ruler can accommodate.
- Measuring Tape: Used in various fields, including tailoring, carpentry, and construction
- Yardstick: Used primarily in the United States for measuring lengths in yards, feet, and inches.
Lesson Presentation (Step-by-Step Procedure)
Step 1: Introduction
Begin with a story about two children who want to know who has the longer pencil. Ask pupils how they think the children can find out.
Step 2: Explanation
Explain that length is the measurement of how long something is from one end to the other. Use simple language and show examples of different objects with varying lengths.
Step 3: Demonstration
Show pupils a ruler, measuring tape, and meter stick. Demonstrate how to use each instrument to measure the length of a pencil, a book, and the classroom door.
Step 4: Guided Practice
Hand out rulers to pupils and guide them in measuring the length of their pencils and notebooks. Provide assistance as needed.
Step 5: Independent Practice
Have pupils measure the length of various objects in the classroom independently, such as their desks, a textbook, and a piece of string.
Step 6: Feedback
Review the measurements taken by pupils. Correct any errors and reinforce the correct usage of the measuring instruments.
Evaluation
- Formative Assessment: Observe pupils during guided and independent practice to ensure they are using the measuring instruments correctly.
- Summative Assessment: At the end of the lesson, provide a worksheet where pupils must measure the length of drawn objects and record their measurements accurately.
Summary/Conclusion
Recap the meaning of length and the names of the instruments used to measure length. Emphasize the importance of accuracy when measuring. Answer any remaining questions from pupils.

Subject: Basic Science
Class: Primary Three
Week of the First Term: 2nd Week
Topic: Measurement of Length
Sub-Topic: Metric Units of Measuring Length (mm, cm) and Reasons for Differences in Length
Instructional Objectives
At the end of the lesson, pupils should be able to:
- Identify and differentiate between millimeters (mm) and centimeters (cm).
- Convert between millimeters and centimeters using simple calculations.
- Explain why different objects have different lengths and provide examples.
Entry Behaviour
Pupils should already know the basic concept of measuring length and have experience using a ruler to measure objects.
Instructional Materials
- Textbook
- Rulers marked with millimeters and centimeters
- Visual aids and charts showing mm and cm units

Content
Metric Units of Measuring Length (mm, cm)
Millimeters (mm)
- A millimeter is a very small unit of length in the metric system. There are 10 millimeters in one centimeter. Millimeters are used to measure very small objects or lengths, such as the thickness of a book’s cover or the diameter of a pencil lead.
Centimeters (cm)
- A centimeter is a unit of length in the metric system. There are 100 centimeters in one meter. Centimeters are used to measure small to medium lengths, such as the height of a water bottle or the length of a pencil
- Reasons for Differences in Length
- Different Objects Have Different Sizes: Just like people come in different heights, objects also come in various lengths. A pencil is shorter than a ruler, and a book is longer than a paperclip.
- Purpose and Function: The length of an object often depends on its purpose or function.
- Design and Practicality: Designers and engineers make objects of different lengths to be practical and useful for their intended tasks.
- Natural Variation: In nature, objects have different lengths due to natural variation and growth patterns.
- Materials Used: The material used to make an object can affect its length. Some materials are better suited for long objects, while others are for shorter ones.
- Measurement and Units: Understanding how to measure lengths and use appropriate units helps us recognize and compare the differences in length.
