Exploring Length with Metre Sticks
Year 3 Mathematics Measuring and Comparing Lengths
What Do You Know About Measuring?
How do we measure how long something is? What tools have you used before? When might we need to measure things?
Meet the Metre!
A metre is a unit for measuring length It's perfect for measuring bigger things One metre is about the height of a kitchen counter We use the letter 'm' to write metres
Let's Measure Together!
Watch how to use a metre stick properly Start at zero Count the metres Record what we find
Our Measuring Words
metre - our unit for measuring length estimate - our best guess before measuring longer - when something is more metres shorter - when something is fewer metres
Group Measuring Challenge
Work in groups of 5 Choose objects to measure Estimate first, then measure Record your findings on the sheet
What Can We Measure?
{"left":"Classroom door\nTeacher's desk\nBookshelf height","right":"Window width\nCorridor width\nWhiteboard length"}
Your Turn to Measure!
Choose an object at your desk Estimate its length in metres Measure carefully with a metre stick Write down both numbers
Let's Share Our Discoveries!
What did you measure? Was your estimate close to the real measurement? What surprised you about measuring?
What We Learned Today
A metre is a unit for measuring length We estimate first, then measure to check Metres are good for measuring classroom objects We can compare lengths using 'longer' and 'shorter'
