NOTE
Length is the measurement of how long or short an object is.
There are two methods for measuring length;
- The olden methods which involve hand span, stride, arm length, etc.
- The standard methods such as tape measure, metre rule, etc.
Metric unit of length
10 millimetres = 1 decimetre
10 decimetres = 1 centimetre
10 centimetres = 1 metre
1000 metres = 1 kilometre
EVALUATION:
- What is length?
- Explain two olden methods and two standard methods of measuring length
- Recite the metric unit of length
CLASSWORK: Similar to the evaluation questions above
