Measure Mass in Kilograms and Grams | Fun and Engaging Key Stage 2 ... - Free Printable

Problem Analysis:

The worksheet is divided into two sections:
1. Section A: Fill in the gaps on each number line.
2. Section B: State the mass of each item in kilograms and grams based on the readings from the scales.

Let's solve each section step by step.

---

Section A: Fill in the gaps on each number line

Each number line ranges from 0 to 1000. The task is to determine the value at each marked point based on equal divisions.

#### 1)
- The number line has 4 equal segments.
- Total range = 1000
- Value per segment = \( \frac{1000}{4} = 250 \)
- Marked points: 0, 250, 500, 750, 1000

#### 2)
- The number line has 6 equal segments.
- Total range = 1000
- Value per segment = \( \frac{1000}{6} \approx 166.67 \)
- Marked points: 0, 167, 333, 500, 667, 833, 1000

#### 3)
- The number line has 3 equal segments.
- Total range = 1000
- Value per segment = \( \frac{1000}{3} \approx 333.33 \)
- Marked points: 0, 333, 667, 1000

#### 4)
- The number line has 5 equal segments.
- Total range = 1000
- Value per segment = \( \frac{1000}{5} = 200 \)
- Marked points: 0, 200, 400, 600, 800, 1000

Section B: State the mass in kilograms and grams of each item

For each item, we need to read the scale and convert the reading into kilograms and grams. Recall that:
- 1 kilogram (kg) = 1000 grams (g)
- The scale needle indicates the mass in kilograms and grams.

#### 1) Tennis ball
- Scale reading: The needle points to 50 g.
- Mass: \( 0 \, \text{kg} \, 50 \, \text{g} \)

#### 2) Aeroplane
- Scale reading: The needle points between 1 kg and 2 kg, closer to 1 kg.
- Mass: \( 1 \, \text{kg} \, 500 \, \text{g} \) (assuming it's halfway between 1 kg and 2 kg)

#### 3) Watermelon
- Scale reading: The needle points to 2 kg.
- Mass: \( 2 \, \text{kg} \, 0 \, \text{g} \)

#### 4) Textbook
- Scale reading: The needle points to 1 kg.
- Mass: \( 1 \, \text{kg} \, 0 \, \text{g} \)

#### 5) Backpack
- Scale reading: The needle points between 1 kg and 2 kg, closer to 1 kg.
- Mass: \( 1 \, \text{kg} \, 500 \, \text{g} \) (assuming it's halfway between 1 kg and 2 kg)

#### 6) Remote control car
- Scale reading: The needle points to 2 kg.
- Mass: \( 2 \, \text{kg} \, 0 \, \text{g} \)

Final Answers

#### Section A
1. \( 0, 250, 500, 750, 1000 \)
2. \( 0, 167, 333, 500, 667, 833, 1000 \)
3. \( 0, 333, 667, 1000 \)
4. \( 0, 200, 400, 600, 800, 1000 \)

#### Section B
1. Tennis ball = \( 0 \, \text{kg} \, 50 \, \text{g} \)
2. Aeroplane = \( 1 \, \text{kg} \, 500 \, \text{g} \)
3. Watermelon = \( 2 \, \text{kg} \, 0 \, \text{g} \)
4. Textbook = \( 1 \, \text{kg} \, 0 \, \text{g} \)
5. Backpack = \( 1 \, \text{kg} \, 500 \, \text{g} \)
6. Remote control car = \( 2 \, \text{kg} \, 0 \, \text{g} \)
