Comparing Volume for low achiever

Learning Outcome:

• To make a perceptual comparison of capacity.

Materials:

• Three drinking glasses of the same size
• Three bowls of the same size
• Three mugs of the same size
• A large water jug

Procedures:

3 Glassses

1. Hold up the three drinking glasses.
2. Ask the students to tell the similarities between the three glasses.
3. Introduce the vocabulary of empty, half full and full.
4. As you introduce the vocabulary, have students come out to fill the glasses accordingly.
5. Have students arrange the glasses in the order from empty to full.
6. Repeat with different sets of container.

Comparing Volume for High Achiever

Learning Outcome:

• To measure volumes of liquid using non-standard units.

Materials:

• Various small containers of different sizes
• A medium pail

Procedures:

example of result recorded

1. Divide the class into groups of five students and have them work in their cooperative groups.
2. Appoint one student in the group to be the recorder.
3. Give each group a set of containers of different sizes and a medium pail.
4. Have the students fill the medium pail with water.
5. Have the students estimate the number of cups needed to contain all the water in the medium pail.
6. Have the students fill the cup to check their estimate.
7. Repeat for the other containers.
8. Have the students record their findings in the following table:
   
   

   Container	Bottle	Glass	Cup
   Estimate
   Measurement

9. Have the students write their findings in the statement below:
   
   The volume of water in the medium pail is the same as the capacity of _____bottles.
   
   The volume of water in the medium pail is the same as the capacity of  _____ glasses.
   
   The volume of water in the medium pail is the same as the capacity of  _____ cups.
10. Have the students discuss about which of the three containers (bottle, glass or cup), has the smallest capacity,

How to Measure Volume of Liquid in different containers

The example of 3 beakers with different volume of liquid

For low achiever... 1. Teacher asks pupils to bring a bottle of mineral water and two different size of transparent containers. 2. Pupils pour the mineral water into two different containers and measure the level of the water.(Teacher puts some colours to the water.)      it looks like the bigger glass holds less water than the smaller glass. 3. Pupils definitely will tell that the smaller glass holds more water if we measure it. 4. Ask pupils to pour the water into the measurement beaker. 5. Now, teacher can show the pupils, how to measure the volume of liquid. Not to looks at the level in different container but by using the standard measurement.

Mathematics Year 2

Volume of Liquid

Volume of liquids means;

1.The capacity of a container is the amount of liquid it can hold.

2. The Unit of volume of liquid are millilitre (ml) and litre (l)

3. 1 litre is equal 1000 millilitre.

4. When measuring liquid using a measuring cylinder, the reading should be taken from where the scale is in the bottom of the meniscus.

Comparing the Volume of Liquid

1.We can compare volume of liquids using units of litres and millilitres.


2. From the above diagrams, we can see that the first container hold more water (7 litre) than second container (4 litre).
3. The above diagram shows container A and B.

i. A holds 1 litre of water.
ii. B holds 600 millilitre of water.
iii. Since, 1 litre is equal to 1000 millilitre. So, container A holds more water than container B.
iv. 1000 ml is more than 600 ml.
