- Students will be able to measure items differently
- Students will solve word problems related to volume
- Students will add and subtract given quantities
- Determine the sum and difference of volume of an item.
- Understanding the standard units of volume.
- Estimate volume of liquids in different vessels
- Picture Cards
- Standard Measuring jar
- Tea cups.
1. Non-Stand Measurement Activity
Teacher can ask students to bring different containers like tumbler, shoe box etc. After this, they can compare these items to show which item has greater/ lesser capacity.
2. Fill it up
Teacher asks student to create paper cylinders there are different size of cylinders and fill them with stone, now, empty the cylinder and count the number of stones. Compare the number of stone. Are they equal or unequal?
3. Compare Your Jug:
The teacher should divide the class into 4 groups and give them different size jugs and mugs. Now, ask them to fill it with water and compare with the other group’s jug.
Teacher can ask the following questions
- Which team has the same water?
- Which team has the least water?
- Who has the maximum water?
The teacher shows model measuring jar in ml and liters. Students have to observe different capacities in ml and liters. The teacher assesses their observation. After this, teacher can give worksheet asking students to solve small problems related to capacity.
Measurements using Standard Measurement objects
In daily life we use different measuring items which are marked in l and ml. teacher can bring in these equipment into classroom and show them to the students. She can explain the following concepts- 250 ml, 500 ml, 1000 ml, 1/4l, 1/2l, 1l.
1l= 1000 ml
1. The teacher gives a work sheet asking students to match appropriately.
- 250 ml - 1l
- 750 ml - 1/4l
- 500 ml - 3/4l
- 1000ml - 1/2l
2. The teacher can circulate worksheet asking students to guess the capacity of the containers.
3. The teacher can ask student to calculate measurements of the following container (e.g. water-battle, bucket etc.,) The teacher gives a worksheet and guess how much water can jugs, mugs, bottles and glasses of different measure hold.
4. Makes liters in different ways.
- 100 ml x 10 = 1000 ml = 1 liter
- 200 ml x 5 = 1000 ml = 1 liter
- 500 ml x 2 = 1000 ml = 1 liter
- 250 ml x 4 = 1000 ml = 1 liter
- 750 ml + 250 ml = 1000 ml = 1 liter
- 300ml + 300ml + 400 ml = 1000 ml = 1 liter

Teacher can give students the above list of items and ask them the below questions
i. List out and draw the odd objects that have the capacity to hold something
ii. Guess the capacity of these items approximately and tabulate them.
|S.No||Name of the Object||Capacity of the Object|
iii. Find the ones odd ones that has maximum capacity.
iv. Discuss the odd item of your choice.
v. Discuss why we can’t fill the items with water
2. Tick the units that would work best for measuring each object.
Glass of milk in early morning
The water used to wash your clothes
The water used for a bath
The water in an ice cube
A big fish tank
The juice squeezed from one orange
An expensive bottle of perfume
Shampoo to wash your hair once
