Measuring tapes

Quick answer

Measuring tapes are flexible rulers that help you find the length, width, or distance of objects. You can use them to measure things like your bed, the length of your garden, or how far you walk to school.

Learning outcome

By the end of this page, you will be able to use a measuring tape to measure the length of objects and calculate the perimeter of shapes in your home or outside.

• You can read numbers on a measuring tape
• You can measure straight lines and curves
• You can add up measurements to find total lengths
• You can use your measurements to solve simple problems

Why this matters

Measuring tapes are super useful in everyday life! When you're helping to build a toy box, planning a garden, or even cooking a recipe, you need to know how long or wide something is. Learning to use a measuring tape helps you understand how big things are and how to compare sizes. It's also a great way to practice counting, addition, and problem-solving.

How it works

Measuring tapes are made of flexible material, like plastic or cloth, and have numbers marked on them. You can bend and stretch them to fit around curved or straight objects. Here's how to use one:

1. Find the start - Look for the zero mark on the tape
2. Place it carefully - Align the zero with one end of what you're measuring
3. Stretch it out - Make sure the tape is straight and not twisted
4. Read the number - Find where the other end reaches on the tape
5. Write it down - Note your measurement in centimetres or metres

Examples you can see

Let's imagine you're helping your parent make a picture frame. You need to measure the length of each side to cut the wood.

To find the perimeter (the total distance around the frame), you add all the sides together:

30 + 30 + 20 + 20 = 100 cm

So the picture frame has a perimeter of 100 centimetres.

Try it as a mini adventure

Adventure: Measure the Garden Path

You're going to help your parent plan a new garden path. You need to measure the path to see how much material you'll need.

1. Step 1: Find the start of the path and place the tape at the beginning
2. Step 2: Stretch the tape along the path and read the measurement
3. Step 3: If the path is 15 metres long, and you want to add a 2-metre border on each side, how long will the whole path be?
4. Step 4: Calculate: 15 + 2 + 2 = ?

Try measuring other things around your house or garden, like the width of your door, the length of your table, or the height of a chair.

Common mistakes

• Mistake: Starting the measurement at the edge of the tape instead of the zero mark
  Why it happens: The tape might have a little bump or tag at the beginning, so children think it's the zero.
  Fix: Always look for the clear zero mark at the start of the tape
• Mistake: Reading the measurement from the wrong side of the tape
  Why it happens: Sometimes the numbers are printed on both sides, and children get confused.
  Fix: Look at the numbers that are clearly visible and easy to read
• Mistake: Not keeping the tape straight when measuring
  Why it happens: It's easier to bend the tape than to keep it straight.
  Fix: Hold the tape firmly and keep it straight along the object
• Mistake: Not counting the full length of the object
  Why it happens: Children might measure from one end to the middle, not the end to the end.
  Fix: Make sure you're measuring from the very start to the very end of the object

Parent and carer guide

Helping your child with measuring tapes is a fun way to practice maths skills. Here's what you can do:

• Start simple: Begin with straight lines and simple shapes
• Use everyday objects: Measure your child's toys, books, or furniture
• Encourage questions: Ask why they think one thing is longer than another
• Make it fun: Turn measuring into a game or challenge
• Check together: Read the measurements aloud and double-check each other's work

Watch for your child to:

• Use the zero mark correctly
• Keep the tape straight
• Add measurements together
• Understand the difference between centimetres and metres

Don't worry if they make mistakes - they're part of learning! Encourage them to try again and explain their thinking.

Practice questions

1. What is the perimeter of a rectangle that is 10 cm long and 5 cm wide?

   Answer: 10 + 10 + 5 + 5 = 30 cm

2. You measure a bookshelf and find it is 200 cm long. How many metres is that?

   Answer: 200 cm = 2 m

3. You have a garden that is 12 m long and 8 m wide. What is the perimeter?

   Answer: 12 + 12 + 8 + 8 = 40 m

4. You measure a table and find it is 150 cm long. How many metres is that?

   Answer: 150 cm = 1.5 m

5. You measure the length of your bedroom and find it is 4 m. How many centimetres is that?

   Answer: 4 m = 400 cm

FAQ

What is a measuring tape used for?

A measuring tape is used to measure the length, width, or distance of objects. It's flexible and can bend around curved shapes.

How do I read a measuring tape?

Look for the numbers on the tape. The numbers show centimetres (cm) and sometimes metres (m). Always start from the zero mark.

Can I measure anything with a measuring tape?

Yes, you can measure almost anything that is straight or curved. You can measure furniture, gardens, clothing, or even your own height.

What is the difference between a ruler and a measuring tape?

A ruler is straight and used for small, straight measurements. A measuring tape is flexible and can bend around objects.

Why is it important to learn how to use a measuring tape?

Learning to use a measuring tape helps you understand how big things are, solve problems, and prepare for more advanced maths in school.
