ACTIVITY 3 : USING NON-STANDARD UNITS AND STANDARD UNITS

Learning Outcomes:


By the end of the lesson, pupils will be able to measure and compare volume of liquids by using standard units and non-standard units correctly.

Prior Knowledge:

Pupils had learnt how to measure volume of liquid using non-standard units and standard units.

Teaching Aids:

Different sizes of containers, 2 measuring cylinders, a pail of water.

Vocabulary:

more, less, empty, half full, full.

Procedures:

1. Divide the pupils into group of four to do work in their cooperative learning.

2. Appoint one student to be the recorder in the group.

3. Give each group 3 set of containers of different sizes, a pail of water and two measuring cylinders. ( One for milliliter and another one for liter)

4. Each group will fill every container with water and state which is more or less.

5. Then, they will measure the volume of liquid in each container in liter and milliliter by pouring the water from the containers into those measuring cylinders.

6. A group member record the results in the form given:

Conclusion:

For this activity pupils know that volume of liquid can be measured by using non-standard units, but the results just under estimation. By using metric units such milliliters and liter we can find more accurate with the results. On the other hand, pupils also able to understand the relationship between both measurement tools.

Summary:

The learning of volume of liquid begins with concrete experience in realistic situations through measuring using both standard and non-standard units. The capacity of liquid in standard units are measured in millimitres(ml) and litres(l) in the metric system. While in non-standard units they are measured using various containers by stated the capacity wheather more or less. Materials from non-standard units are easier to obtain. It is good to give children experience with unfamiliar systems of measurement .
