This worksheet helps students practice measuring liquid volume in milliliters by filling jugs and calculating remaining capacity.

Problem Analysis:

The worksheet focuses on understanding volume and capacity, specifically in milliliters (ml). The tasks involve reading measurements from measuring jugs, calculating the amount of liquid needed to fill each jug to 1 liter, and determining how many 250 ml jugs are required to fill a bucket with a 9.5 L capacity.

Step-by-Step Solution:

#### Part 1: Colour to Fill Each Measuring Jug to the Levels Indicated Below
This part asks you to color the measuring jugs to the specified levels:
- 500 ml: Color up to the 500 ml mark.
- 750 ml: Color up to the 750 ml mark.
- 250 ml: Color up to the 250 ml mark.
- 1000 ml: Color up to the 1000 ml mark.

Explanation: This is a straightforward task where you visually represent the given volumes by coloring the jugs to the correct level.

#### Part 2: How Many Milliliters of Liquid Are in Each of These Measuring Cups?
Here, you need to read the liquid levels in the measuring cups and write down the corresponding volumes.

1. First Cup: The liquid reaches the 400 ml mark.
- Answer: 400 ml

2. Second Cup: The liquid reaches the 650 ml mark.
- Answer: 650 ml

3. Third Cup: The liquid reaches the 200 ml mark.
- Answer: 200 ml

4. Fourth Cup: The liquid reaches the 800 ml mark.
- Answer: 800 ml

Explanation: For each cup, observe the liquid level and match it to the scale on the side of the measuring cup.

#### Part 3: How Much Liquid Is Needed to Fill Each Jug to 1 Litre?
This part requires calculating the additional amount of liquid needed to fill each jug to 1 liter (1000 ml).

1. First Jug: Current level = 700 ml
- Additional liquid needed = \( 1000 \, \text{ml} - 700 \, \text{ml} = 300 \, \text{ml} \)
- Answer: 300 ml

2. Second Jug: Current level = 500 ml
- Additional liquid needed = \( 1000 \, \text{ml} - 500 \, \text{ml} = 500 \, \text{ml} \)
- Answer: 500 ml

3. Third Jug: Current level = 800 ml
- Additional liquid needed = \( 1000 \, \text{ml} - 800 \, \text{ml} = 200 \, \text{ml} \)
- Answer: 200 ml

4. Fourth Jug: Current level = 650 ml
- Additional liquid needed = \( 1000 \, \text{ml} - 650 \, \text{ml} = 350 \, \text{ml} \)
- Answer: 350 ml

Explanation: Subtract the current liquid level from 1000 ml to find the additional amount needed.

#### Part 4: Colour the Amount Needed to Fill the Bucket
The bucket has a capacity of 9.5 liters (9500 ml). You need to determine how many 250 ml jugs are required to fill the bucket.

1. Calculate the total number of 250 ml jugs needed:
\[
\text{Number of jugs} = \frac{\text{Bucket capacity}}{\text{Volume of one jug}} = \frac{9500 \, \text{ml}}{250 \, \text{ml}}
\]
\[
\text{Number of jugs} = 38
\]

2. Color the appropriate number of jugs:
- There are 38 boxes representing the jugs. Color all 38 boxes to indicate that 38 jugs are needed.

Explanation: Divide the total capacity of the bucket by the volume of one jug to find the number of jugs required.

Final Answers:

1. Part 1: Color the jugs to the specified levels (500 ml, 750 ml, 250 ml, 1000 ml).
2. Part 2:
- First cup: 400 ml
- Second cup: 650 ml
- Third cup: 200 ml
- Fourth cup: 800 ml
3. Part 3:
- First jug: 300 ml
- Second jug: 500 ml
- Third jug: 200 ml
- Fourth jug: 350 ml
4. Part 4: 38 jugs are needed to fill the bucket. Color all 38 boxes.
