Educational worksheet for identifying measuring tools and their functions.

Let's solve each part of the worksheet step by step.

1. Choose the correct names for these tools

We are given 5 images, and we need to match each image with its correct name from the list:
thermometer, measuring cup, scale, hand lens, tape measure

Here are the images and their correct labels:

1. First image (magnifying glass) → hand lens
2. Second image (clear cup with measurement lines) → measuring cup
3. Third image (temperature gauge with red line and numbers) → thermometer
4. Fourth image (red and silver weighing device) → scale
5. Fifth image (yellow flexible ruler) → tape measure

✔ So the correct matching is:
- Image 1: hand lens
- Image 2: measuring cup
- Image 3: thermometer
- Image 4: scale
- Image 5: tape measure

2. Complete the sentences

Now, fill in the blanks using the correct tool names:

- A hand lens helps you observe more details than with your own eyes.
*(A magnifying glass lets you see small things more clearly.)*

- We use a thermometer to measure temperature.
*(Thermometers show how hot or cold something is.)*

- We use a measuring cup to measure amounts of liquids.
*(Measuring cups have volume markings for liquids like water or milk.)*

- We use a tool called a scale to measure weight.
*(Scales tell us how heavy something is.)*

- We use a tape measure to measure length, width and height.
*(Tape measures are flexible rulers used for long distances.)*

✔ Final answers:
- hand lens
- thermometer
- measuring cup
- scale
- tape measure

3. Name the parameters of the rectangular prism

A rectangular prism is a 3D shape with six rectangular faces. The three main dimensions (parameters) that define it are:

- Length – the longest side of the base
- Width – the shorter side of the base (perpendicular to length)
- Height – the vertical dimension (how tall it is)

These three measurements are needed to calculate volume and surface area.

✔ So, the parameters are:
Length, Width, Height

✔ Final Answers Summary:

#### 1. Match the tools:
1. Hand lens
2. Measuring cup
3. Thermometer
4. Scale
5. Tape measure

#### 2. Complete the sentences:
- A hand lens helps you observe more details than with your own eyes.
- We use a thermometer to measure temperature.
- We use a measuring cup to measure amounts of liquids.
- We use a tool called a scale to measure weight.
- We use a tape measure to measure length, width and height.

#### 3. Parameters of a rectangular prism:
- Length, Width, Height
