Measuring Metres

Overview

Today students learn to measure and record length using metres, using rulers/measuring tools with clear marking and correct unit language. They will practise expressing lengths as metre measurements through guided and independent tasks.

Learning intentions

• WALT introduce measuring length using metres.
• Students will use measuring tools to find how many metres a distance/object is.
• Students will record results using the correct unit (metres) and compare lengths.

Success criteria

• I can measure a length using a ruler/measuring tape and read the metre units.
• I can write a measurement in metres (for example, 1 m, 2 m).
• I can check my measurement by re-measuring or estimating if it makes sense.

Curriculum links

• Students develop understanding of measuring length using appropriate units and measuring tools.
• Students estimate, measure, and compare lengths in everyday contexts.
• Students represent measurements using numbers and units and communicate findings clearly.

Lesson structure (30 minutes)

1. 4 minutes – Hook with a “How long?” challenge Show two classroom items (e.g., bench strip, book shelf segment) and ask which is longer. Introduce the idea that we measure distance using a unit called a metre.

2. 6 minutes – Explicit teaching: metres and the measuring process Model measuring one item slowly:

• Place the start of the measuring tool at the beginning of the object.
• Keep the tool straight and aligned with the length.
• Read the marking at the end of the object. Use clear language: “I measured __ metres.”

3. 8 minutes – Shared practice: “Measure with me” stations (whole class) Students work together on one short strip of known metre steps (e.g., masking tape line with metre marks). Call on students to help place the measuring start and read the metre marking. Confirm correct unit language and record as a class on a simple chart (Length / Measurement in metres).

4. 8 minutes – Independent/paired task: measure and record Students (in pairs) measure 2–3 objects/lines around the room that can be done within a metre range (e.g., classroom mat edge, desk width segment, taped line sections). They record each as a number and “m”. Provide a recording sheet with sentence frames such as: “My object is ___ metres long.”

5. 3 minutes – Quick check and share-out Have 3–4 pairs share one measurement each. Ask: “Does it make sense? Is it closer to 1 m or 2 m?” Reinforce re-checking if results seem unreasonable.

6. 1 minute – Exit ticket (teacher checks understanding) Students hold up their measuring card/measurement strip showing one metre-based measurement they completed. Teacher does quick scanning for correct unit and reading.

Resources

• Rulers and metre measuring tapes (short versions where possible)
• Masking tape or paper strips to create a measuring line on the floor/wall with metre marks
• Object set for measurement (e.g., book, box edges, mat segment, laminated strip)
• Student recording sheets with space for 2–3 measurements
• Pencils/coloured pencils
• Visual number line/metre strip display (large and clear)
• Sentence frames for recording (e.g., “It is __ metres long.”)
• Timer for task rotation (if needed)
• Clipboards or flat boards for students to write on

Assessment

• Teacher observation during measuring: correct tool placement, alignment, and correct unit language.
• Review of recorded answers on the student sheets (number accuracy and inclusion of metres).
• Exit ticket: quick check that students can express a measured length in metres.

Differentiation

• Visual supports: metre strip on the floor/wall, large metre markings, and a model measurement example visible throughout.
• Support for neurodivergent learners: short, structured steps with clear “stop points” (place start, align, read end, record).
• EALD support: sentence frames and repeated oral modelling (“__ metres long”) plus showing not just telling.
• Need more support: allow measuring with buddy assistance and use objects that are close to whole-metre lengths to reduce fine reading demands.
• Extension for advanced learners: after measuring, estimate then justify by measuring again (e.g., “I thought it was 2 m, but it is 1.8 m—why might my estimate be close or not?”). Also measure one additional item and compare: “Which is longer and by how many metres?”
