For Teachers

Primary 1: Length_Interactive board using non-standard units to measure the length of object



In this lesson, you will learn to
- measure some objects using the virtual paper clips as non-standard units.
- use the word unit to measure length
- estimate the length of objects with number of units


Before you use the interactive board to explore and measure objects using the paper clips,
please refer to the explanation below to understand how the different buttons work.






It's exploration Time!

After you have read the explanation of the different buttons, please explore to estimate the length of different objects using the paper clips.
Note: The objects used here are for illustration only, it is not the actual size of the object.



What have you learned about length?


1. I must use the ___________ non-standard units when comparing the length of objects.
2. I learn words like _____________ when comparing the lengths of objects.
3. When measuring length, the units must be placed end-to-end without __________________.

Suggested Answers

I must use the same non-standard units when comparing the length of objects.
2. I learn words like long/longer/longest/short/shorter/shortest (any reasonable answer) when comparing the lengths of objects.
3. When measuring length, the units must be placed end-to-end without gaps or overlaps (can accept 'space').
