Whose Jug Holds More?
If Naima pours one glass of water in her jug, it looks like this:
Naima thinks she will have to pour around 3 glasses of water to fill the jug.
- What do you think?
If Jeetu pours one glass of water in his jug, it looks like this:
- Whose jug holds more water?
- How many glasses of water do you think Jeetu should pour to fill his jug?
- If Jeetu pours one more glass of water his jug will be around ______ full.
- Naina is correct. It will take 3 glasses to fill the jug.
- Jeetu’s jug holds more water.
- Jeetu should pour about 3 more glasses of water to fill his jug.
- If Jeetu pours one more glass of water, his jug will be around half full.
Filling Pots
Naseem and Abdul had to fill their pots each with water. Both pots were equally big and heavy. So, they went to the tap again and again, filled their own bottles and poured water into the pots.
Naseem had to fill her bottle 16 times from the tap. But Abdul
had to fill his bottle only 8 times.
a)Why did Naseem go more times than Abdul?
b) Naseem's bottle can hold (twice/half/three times) as much water as Abdul's bottle.
- Naseem is filling her pot with a bottle. Her bottle is smaller than Abdul’s bottle. So, she is taking more time than Abdul to fill the pot.
- Naseem has to go 16 times to the tap to fill her bottles whereas Abdul has to go 8 times to fill his bottle. Since
16 = 2 × 8
Abdul’s bottle can hold twice the water as Naseem’s bottles.
Therefore, Naseem’s bottle can hold half of the water Abdul’s bottle can.
How Many Glasses?
Pot B holds 11 glassfuls of water. Pot A holds twice as much water as pot B. How many glasses of water are needed to fill pot A?
Capacity of Pot A is twice that of Pot B. Since capacity of Pot B is 11 glasses of water, twice the capacity of pot B is:
11 × 2 = 22
Therefore, 22 glasses of water are needed to fill up Pot A.
Filling Potholes
This is a small town near Kohima. There are some potholes in the road. Before the rains come, children want to fill the holes with pebbles. They bring pebbles in mugs of the same size.
Hole A gets filled with 9 mugs of pebbles.
Hole B gets filled with 18 mugs of pebbles.
Hole C gets filled with 12 mugs of pebbles.
- Mark A, B, C on the right hole in the picture.
- Which is the biggest pothole?
- If jugs are used, hole A gets filled with 5 jugs. How many jugs of pebbles are needed to fill hole B?
Since hole B gets filled with 18 mugs, C with 12 mugs, and A with 9 mugs of pebbles, mark the biggest path hole with B, the bigger one with C and the smaller one with A.
- B is the biggest pothole.
- 9 mugs fill up hole A and 18 mugs fill up hole B. Since
18 = 2 × 9,
hole B is twice as big as hole A.
Since 5 jugs can fill up the hole A, twice of 5 jugs are needed to fill up hole B.
2 × 5 = 10
Therefore, 10 jugs of pebbles are needed to fill up hole B.
