-Identify the kilogram as a standard unit of measuring mass
-Compare different masses with a kilogram

Why do we need standard units to measure mass?

Measurement

Mass - Measuring in kilograms

By the end of the lesson, the learner should be able to:

-Measure mass of different objects in kilograms
-Use kilogram weights appropriately
-Appreciate measuring mass in kilograms

-In pairs/groups, measure the mass of different objects in kilograms using 1 kilogram weights
-Record the measurements in kilograms
-Visit a shop or market and observe how kilograms are used

How do we measure mass using kilogram weights?

Measurement

Mass - Comparing masses

By the end of the lesson, the learner should be able to:

-Compare masses of different objects
-Use terms heavier than, lighter than, same as
-Value the importance of comparing mass

-Measure and compare masses using a beam balance
-Use terms like 'heavier than', 'lighter than', or 'same mass as'
-Record and discuss comparisons

How do we compare the masses of different objects?

Measurement

Mass - Real life applications

By the end of the lesson, the learner should be able to:

-Apply mass measurement in real life
-Assist vendors in measuring items
-Appreciate the use of mass measurement

-Visit a shop or market and assist vendors in measuring items such as beans, maize, rice, flour using fixed units
-Discuss where mass measurement is used in daily life
-Role play scenarios involving measuring mass

How do we use mass measurement in our daily lives?
