Worksheet for children to choose the best unit of measurement for different items and activities.

Let's solve the problem step by step.

The task asks you to choose the best unit of measurement (from grams, litres, metres, centimetres, millilitres, or kilograms) for each object listed. The goal is to match each object with the most appropriate unit based on what we're measuring (weight, length, volume, etc.).

Here’s the table from the image:

| Object | Best Unit |
|--------|-----------|
| The weight of a piece of cheese | ? |
| The length of a house | ? |
| The width of your hand | ? |
| The water in a tub | ? |
| Your weight | ? |
| The weight of a carrot | ? |
| A teaspoon of medicine | ? |

Now let’s go through each one and explain why we pick a certain unit.

1. The weight of a piece of cheese
→ Grams
*Explanation:* Cheese is light, but not extremely small. Grams are used for small weights like food items. Kilograms would be too large for a single piece.

2. The length of a house
→ Metres
*Explanation:* Houses are large structures, so we use metres to measure their length. Centimetres would be too small and impractical.

3. The width of your hand
→ Centimetres
*Explanation:* Hands are small, but not tiny. Centimetres are ideal for body parts like hands. Millimetres are too precise for this context.

4. The water in a tub
→ Litres
*Explanation:* Water volume is measured in litres. A bathtub holds many litres, not millilitres (which are too small) or kilograms (which measures weight, not volume).

5. Your weight
→ Kilograms
*Explanation:* Human body weight is typically measured in kilograms. Grams would be too small (e.g., 70,000 grams = 70 kg).

6. The weight of a carrot
→ Grams
*Explanation:* A carrot is light, similar to a piece of cheese. Grams are perfect for such small objects.

7. A teaspoon of medicine
→ Millilitres
*Explanation:* Liquid medicine in a teaspoon is measured in millilitres (mL), which is a small unit of volume. Litres are too big.

Final Answer Table:

| Object | Best Unit |
|--------|-----------|
| The weight of a piece of cheese | grams |
| The length of a house | metres |
| The width of your hand | centimetres |
| The water in a tub | litres |
| Your weight | kilograms |
| The weight of a carrot | grams |
| A teaspoon of medicine | millilitres |

✔ This matches common real-world measurement practices!
