Performance objectives

• By the end of this week, learners should be able to:
• Estimate and measure length, mass, and capacity using simple non-standard units (e.g., hand spans, blocks, cups).
• Compare and order objects based on their length, mass, and capacity (e.g., longer/shorter; heavier/lighter; holds more/holds less).
• Describe the length, mass, or capacity of objects using appropriate vocabulary.
• Introduce and use standard units for measurement: metre (m), kilogram (kg), and litre (L).

Lesson summary

Introduction This week, we dive into the exciting world of Measurement! Measurement is a practical and essential mathematical skill that we use every single day. For our Grade 2 learners in South Africa, understanding measurement helps them make sense of the world around them. Whether they are helping Gogo in the kitchen, playing soccer on the field, or going to the spaza shop, they are constantly comparing sizes, weights, and amounts.

This lesson focuses on three key areas: Length: How long or short is something? How far is it from here to there?

Mass: How heavy or light is an object?

Capacity: How much can a container hold?

Lesson notes

This section breaks down the core ideas of length, mass, and capacity. It is vital to use practical, hands-on activities throughout these explanations. A. Length (How long is it?) Length tells us the distance from one point to another. It helps us understand how long, short, wide, or tall something is. Non-Standard Units Before we use rulers, we can use things around us to measure. These are called non-standard units.

Why we use them: They are easy to find and help us understand the idea of measuring.

Examples: Hand spans, pencils, crayons, footsteps (paces), building blocks.

How to use them: Choose your unit (e.g., a pencil). Place the unit at the start of the object you are measuring. Mark where it ends. Move the unit to the end mark and repeat. Count how many times you used the unit.

The Problem with Non-Standard Units: The biggest challenge is that they are not all the same size! My hand span is bigger than a Grade 2 learner's hand span. Your pencil might be shorter than your friend's pencil. This means we will get different answers when measuring the same thing. This is why we need standard units.
