Lesson Duration: 45 minutes
Week & Period: Week 26, Period 5
Topic: Measurement
Sub-topic: Understanding Weight (Mass) and Capacity
Learning Objectives
By the end of the lesson, students should be able to:
Describe the concept of weight/mass
Describe the concept of capacity
Estimate weight and capacity using non-standard and standard units
Previous Knowledge
Students already know how to carry and compare objects by feel (light and heavy).
Instructional Materials
Stones, bags, bottles, buckets, cups, spoons, water
Lesson Development – ABC Model
A – Anticipation (Warm-up / Starter)
Time: 5–10 minutes
The teacher lifts a school bag and a stone, asking: “Which one feels heavier?” Learners respond.
B – Building Knowledge (Main Lesson Body)
Time: 25–30 minutes
Weight/Mass: Weight is how heavy or light an object is.
Non-standard measurement: using hands to feel weight, comparing two bags.
Standard measurement: using a scale, kilogram (kg).
Capacity: Capacity is the amount a container can hold.
Non-standard measurement: using cups or spoons to fill a bucket.
Standard measurement: using litres (L).
Examples:
Compare the weight of learners’ bags.
Estimate capacity of a water bottle using cups.
Fill a bucket with bottles of water to estimate its capacity.
Learners’ Activities (Expanded):
Learners lift two objects and decide which is heavier.
They pour cups of water into a bottle and count.
They estimate which bucket can hold more water.
Assessment Checks:
What is weight?
What is capacity?
Give one example of a heavy object and a light object.
Notes (Expanded & Detailed):
Weight tells us how heavy something is. Capacity tells us how much a container can hold. We can use hands, cups, and spoons (non-standard) or scales and litres (standard).
C – Consolidation (Conclusion & Assessment)
Time: 5–10 minutes
Summary: Weight is how heavy or light an object is. Capacity is how much a container can hold.
Evaluation Method (Expanded):
Exit slip: Write one object that is heavy and one that is light.
Assignment (Expanded):
At home, use a cup to measure how many cups of water can fill your drinking bottle.
Follow-up Activity:
Bring an empty container from home to use in class.
Differentiation / Inclusive Strategies
Provide smaller containers for weaker learners. Use peer support for practical tasks.
