Filling and Lifting

Given: When the milk from all three glasses is poured into same-sized glasses, we can compare the levels directly.

From the picture, Ritu's same-sized glass shows the highest milk level.

Answer: Ritu drank the most milk.

Given: The three same-sized glasses show different levels of milk after pouring.

From the picture, Monu's same-sized glass shows the lowest milk level.

Answer: Monu drank the least milk.

Concept: We compare the levels of milk in the same-sized glasses after pouring.

From the picture, the order from most to least is: Ritu > Nita > Monu.

(a) Nita's glass holds more milk than Monu's glass.
(Reason: Nita's level is higher than Monu's level.)

(b) Monu's glass holds less milk than Nita's glass.
(Reason: Monu's level is lower than Nita's level.)

(c) Ritu's glass holds more milk than Nita's glass.
(Reason: Ritu's level is the highest of all three.)

Concept: The glass whose same-sized comparison glass has the highest level holds the most milk, and the one with the lowest level holds the least.

(a) ☑ Ritu's glass holds the most milk.

(b) ☑ Monu's glass holds the least milk.

Concept: Among the three vessels — small bowl, glass, and bottle — the bottle is the largest and the small bowl is the smallest. The glass is in between.

(a) The glass holds the least water.
(Note: Among glass and bottle, the glass holds less. If the small bowl is the reference unit, the glass holds more than the bowl but less than the bottle. Based on the activity context where the glass is being filled by bowls and the bottle by glasses, the glass holds less than the bottle.)

Standard expected answer based on the activity:
(a) The glass holds the least water. *(smallest vessel among glass and bottle)*
(b) The bottle holds the most water. *(largest vessel)*

This is an activity-based/open-ended question. Students should look around their homes and identify larger vessels.

Sample Answer: Vessels that can store more water than a bottle include:
- Bucket
- Drum / large container
- Matka (earthen pot)
- Large jug or pitcher
- Overhead water tank

*(Answers will vary depending on the bottle size and vessels available at home.)*

This is an activity-based question that depends on the sizes of the ladle and bowl shown in the picture.

Concept: A ladle is smaller than a bowl, so several ladles are needed to fill the bowl.

Sample Answer: Based on the picture, approximately 4 ladles fill the bowl.
*(Actual answer depends on the sizes shown in the figure. Students should pour water using the ladle into the bowl and count the number of times.)*

This is an activity-based question depending on the sizes shown in the picture.

Concept: A jug holds more water than a glass, so it can fill multiple glasses.

Sample Answer: Based on the picture, the jug can fill approximately 4 glasses.
*(Students should pour water from the jug into the glass and count how many full glasses are obtained.)*

Concept: To fill half a glass, we need a vessel that holds about half the capacity of the glass.

Answer: We can use a ladle to fill half of the glass, since a ladle holds less water than a full glass. Pour ladles one at a time until the glass is half full.

Answer: We would use the jug for distributing lemonade in glasses.

Reason: The jug holds more lemonade than a glass or a bowl, so it is easy to pour from the jug into each glass without having to refill frequently. It is also convenient to hold and pour.

Given: From Question 2, 1 jug fills 4 glasses.

Formula: Number of glasses = Number of jugs × Glasses per jug

$$\text{Number of glasses} = 3 \times 4 = 12$$

Answer: 3 jugs of lemonade can fill 12 glasses.

Given: From the activity, suppose 1 glass = 2 ladles (based on the picture).

Formula: Total ladles = Number of glasses × Ladles per glass

$$\text{Total ladles} = 4 \times 2 = 8$$

Answer: 8 ladles are needed to fill 4 glasses.
*(The exact number depends on the sizes shown in the figure. Students should use their measured value from the activity.)*

Answer: Yes, we can use a ladle, bowl, or glass to find out how much lemonade a jug can hold.

Method:
- Fill the ladle (or bowl or glass) with water/lemonade.
- Pour it into the jug.
- Count how many times you pour until the jug is full.
- That count tells you the capacity of the jug in terms of ladles (or bowls or glasses).

Conclusion: Utensils with less capacity can be used to measure a utensil of larger capacity by counting how many times the smaller vessel fills the larger one. The total quantity of liquid remains the same.

Given: Nita uses a 1 litre bottle to compare with the jug, glass, and bowl.

From the picture:
- The glass is smaller than the 1 litre bottle.
- The bowl is smaller than the 1 litre bottle.
- The jug holds exactly the same amount as the 1 litre bottle.

(a) The glass holds ☑ less than 1 litre.

(b) The bowl holds ☑ less than 1 litre.

(c) The jug holds ☑ exactly 1 litre.

Activity-based question. Students should take their 1 litre bottle and pour water into various vessels at home.

Method: Pour 1 litre of water from the bottle into the vessel. If the vessel is exactly full (neither overflowing nor partially empty), it holds exactly 1 litre.

Sample Answer: Vessels that are commonly exactly 1 litre:
- A standard 1-litre milk packet or bottle
- Some medium-sized jugs
- Certain cooking oil bottles

*(Answers will vary based on vessels available at home.)*

Activity-based question. Students should use the 1 litre bottle to check.

More than 1 litre (sample answers):
- Bucket
- Large jug
- Cooking pot
- Water bottle (large)

Less than 1 litre (sample answers):
- Drinking glass
- Small bowl
- Cup / mug
- Ladle

*(Answers will vary based on vessels available at home.)*

Concept:
- 1 litre = 2 half litres = 4 quarter litres
- From the picture, the mug is filled exactly halfway when 1 litre is poured, and the glass is filled exactly when a quarter litre is poured.

(a) The mug holds ☑ half litre of water.

(b) The glass holds ☑ quarter litre of water.
